B. y=5x+14
You can first find the gradient (m) of the line by using the equation m= Y2-Y1 / X2-X1.
(-2 ,4) (-3,-1)
I'll take -1 as Y2
4 as Y1
-3 as X2
-2 as X1
m= -1 - 4 /-3 - (-2) =5
so 5 is the gradient ...
Then, take any of the two coordinates and substitute in the equation y=mx+c and find C value
If u take (-2 ,4)
Y= 4 , X= -2 , m=5 (we found)
Y=mx+C
4= 5×-2 +C
C=4+10
so C =14
Then we get the answer with the gradient m = 5 and C =14
Y =5X + 14
