A scale factor of 4. This is a simple dilation problem.
point slope form of a line
y-y1 = m(x-x1)
y-7 = -2 (x-1)
if you want it in slope intercept form
y-7 = -2x +2
add 7 to each side
y = -2x +9
The answer would be 7. The two minus signs cancel each other out and turn into a plus sign.
Answer:
0
Step-by-step explanation:
The slope of the line is zero because it is a horizontal line with no rise or fall.
