We can find the b-value, the y-intercept, by looking at the graph and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for. The straight line on the graph below intercepts the two coordinate axes. We can use the characteristics of intercepts to quickly calculate them from the equation of a line. Just see how easy it is, as we find the x- and y-intercepts for the line. In the previous lesson, you learned how to graph points on the coordinate plane. Subtract the y value of point A from the y-value of point B to find the change in.
Find the y-intercept of this line using the Replace x and y with the coordinates of the. Question Find the x- and y- intercepts of the line using these coordinates, (–2, –5) and (6, 1). Answer STEP 1: Before getting started. number b is called the y-intercept of the line. and only if the coordinates of that . Students are able to derive linear equations using the point-slope formula.
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know two points that a line passes through, this page will. Solve for b by plugging m and one set of coordinates into the formula for a line: y = mx y=-x+1. Using the point-slope form, we can see that the y-intercept is 1.
