Write an equation in slope-intercept form of a line containing the point (10,-12) and (13,18).


First, we get the Slope via Point-Slope Form:

red%28m=10%29


Then, thru point (10,-12) in Slope-Intercept Form:
y=mx%2Bb
-12=10%2810%29%2Bb ---> 12=100%2Bb
b=-12-100=red%28-112%29, Y-Intercept

Also, thru point (13,18): (should be the same)
18=10%2813%29%2Bb
18=130%2Bb
b=18-130=red%28-112%29

Therefore, it follows, y = 10x - 112, Answer
