Answer:
y= -2x-1
Step-by-step explanation:
In solving, find the gradient from coordinates given , then use the gradient with one of the pairs to find the equation in form of y=mx+c
finding the gradient
points(-2,3) and (1,-3)
m=change in y/change in x
change in y=-3-3=-6
change in x=1--2=3
m=-6/3 =-2
taking the coordinates (1,-3) and (x,y), the equation will be
y=mx+c, where m=-2
(y--3)/(x-1) =-2
(y+3)/(x-1)= -2
(y+3) = -2(x-1)
y+3=-2x+2
y=-2x+2-3
y= -2x-1
