Answer:
y = 0
Step-by-step explanation:
y = mx + c
M is taken as gradient.
Gradient is equals y difference ÷ x
difference
Y difference = 0
X difference = 0 - (-3) = 3
Hence the gradient here is 0
Let us take the co ordinates (0,0) (you can take any of the coordinates given)
Substitute the equation:
y = mx + c
0 = 0×0 + c
C = 0
Hence y = 0 is the answer
So hence the values of y co ordinates lie on 0
