Which is the equation of the line through (1 11) and (-2 2)

y=3x+8

Step-by-step explanation:

(1 11) and (-2 2)

Find slope first "m"

M= y2-y1/x2-x1

M= 2-11/-2-1

M= -9/-3

M=3

Now use one the points with slope to find b

Y=mx +b with point (1,11) and slope 3.

Y=mx+b

11=3(1)+b

11=3+b

11-3=b

8=b

Now substitute to make equation

Y=3x+8
