I don't know if you have a graph innfront of you or not but the lone will take it from quadrant 3( the bottom left) to quadrant 1 ( upper right ) where it crosses To go from negatave to positive is your y intercept. sorry if that is kinda confusing
We first calculate the slope of the line using m = (change in y)/(change in x) m = (4 - (-2))/(2 - (-2)) m = 6/4 = 3/2 y = mx + c, we use the point (2 , 4) to help calculate the y-intercept, c 4 = 3/2 (2) + c c = 1 The y-intercept = (0 , 1)
