Answer:
Step-by-step explanation:
so use the change formula: Δy/Δx
since you have two point the formula would be like this:
ysub2-ysub1/ xsub2-xsub1
(-9,-3)(-2,6)
x1,y1 x2,y2
6-(-3)/-2-(-9)
9/7= slope
slope intercept form is y=mx+b
so i chose (-2,6)
6=-2(9/7)+b
6=-18/7+b
42+18=7b
60/7=b
now put everything together:
y=mx+b
y=9/7+60/7
