How will the graph of line y = -5x + 7 be affected if the 7 is changed to –7? A. The line will be reflected over the x-axis.
B. The line will be reflected over the y-axis.
C. The line will be rotated 90° about the origin.
D. The y-intercept will be moved 7 units downward.

E. The y-intercept will be moved 14 units downward.

Answer is D

the reason it's because you only changed the Y intercept number to a negative so it will shift down the graph 14 units because if you have no adding number then your graph will start at 0 but it's -7 so it starts at -7 so now shift 14 places down

the answer is d on edge

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
