<span>The coordinate rules when making 2 similar shapes since the shapes are the same</span>
The answer is 9 because 36 divided by 4 is 9.
Have a great day.
Y = mx + c
Where
y is the y of (2, -8)
x is the x of (2, -8)
m is the gradient or slope
c is the y intercept (you don’t know what it is)
Put into equation and find c
Once find c rewrite the equation with only the m and c in numbers
Eg
y = 5x + 3 (this is an example not the answer)
