How to find y intercept from two points.

In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.. There are basically two intercepts, x-intercept and y-intercept.Given the equation y = m*x + b, where m is the slope and b is the y-intercept, you already have y, m, and x (just plug in X1, Y1), so you can solve for b. – Reinstate Monica -- notmaynard Nov 13, 2013 at 17:18Learn how to write an equation for a line given two points on it. The video shows how to find the slope and the y-intercept using the slope-intercept form y=mx+b.The vertical distance between the two points you know is 30 30 (from 50 − 20 50 − 20 ). So the y y -coordinate you are looking for is 65.75% 65.75 % of 30 30, or about 19.725 19.725, units up from 20 20. So the answer is about 39.725 39.725. Share.

How the equation of a line relates to the graph of its y-intercept. The Y-Intercept of a line is the point where a line 's graph intersects (crosses) the Y-axis. A y-intercept of 3 means that a line's graph intersects the Y-axis at the point (0, 3). A y-intercept of -4 means that the graph of a line crosses the Y-axis at the point (0, -4). 2 Answers. The equation must be of the form a(x − h2)(x − h) a ( x − h 2) ( x − h) with a ≠ 0 a ≠ 0. Using the point (0, 1) ( 0, 1) we get that. so a = 2/h2 a = 2 / h 2 (assuming that h > 0 h > 0 ). You are close. The quadratic is of the shape y = A(x − h/2)(x − h) y = A ( x − h / 2) ( x − h), where A A is a constant.The y-intercept is the point where the graph of a line intersects the y -axis. These points have the form (x, 0) and (0, y), respectively. Figure 3.3.1. To find the x - and y -intercepts algebraically, use the fact that all x …

4. Plug in the point's x- and y-values. This will make the equation ready to be solved. Solving it will lead to the y-intercept's value being found. [2] 5. Solve the equation. Multiply the new slope with the x-value. Then, cancel out the product (make it become 0) with either addition or subtraction.Hello, I was wondering if there is an easy way to find the slope and intercept of a line using MATLAB, like how it is so easy with Excel where you just plot the data and add a trendline, so then it will tell you the slope and intercept. Here is my code. Theme. Copy. tau = [15, 38, 100, 300, 1200]; CA = [1.5 1.25 1 0.75 0.5];Thus, we have the point (3 2, 0). So, if x = a = 3 2, y = 0. Construct a coordinate system, plot these two points, and draw a line through them. Keep in mind that every point on this line is a solution to the equation y − 2x = − 3. Example 7.4.2. − 2x + 3y = 3. To find the y -intercept, let x = 0 and y = b.The y-intercept is the y-coordinate when x=0, and the x-intercept is the x-coordinate when y=0.

Same goes for the next question, while there are other points that …In mathematics, linear refers to an equation or function that is the equation of a straight line and takes the form y = mx + b, where “m” is equal to the slope, and “b” is equal to...By putting the x and y values for the two points into the slope equation the value for m can be found. The equation of a line in the slope intercept form is. y = mx + b. After finding m using the slope equation substitute one set of point values for y and x. This leaves b as the only unknown. Slope the resulting equation for b.The x-intercept is (-1/2, 0) creating the second point needed to find the slope. I will now solve the given equation for y. -2x + y = 1. y= 2x + 1. The equation I need to find can be found by finding the slope using (-1/2, 0) and (6, 2). I then plug one of the points and the slope into the point-slope formula. Recall that the slope of a line is the ratio of the change in y over the change in x between any two points on the line: Slope = Change in y Change in x. Therefore, this is the slope between the points ( 0, 3) and ( 2, 7) : m = Change in y Change in x = 7 − 3 2 − 0 = 4 2 = 2. In conclusion, the equation of the line is y = 2 x + 3 . He is not using "b" at this time as the y-intercept. Remember, a y-intercept will always have an X-value = 0 because the point must sit on the y-axis. The point (-3, 6) that Sal used to find the equation clearly is not on the y-axis, so it can not be the y-intercept for the line. Once the equation is changed into slope-intercept form, the y ...
