Answer:

y = 9

Step-by-step explanation:

The line x = -7 is a vertical line, so the perpendicular line will be horizontal.

Horizontal lines have a slope of 0.

Using this slope and the point given, plug them into y = mx + b to solve for b and create the equation

y = mx + b

9 = 0(4) + b

9 = b

Plug this and the slope into the equation:

y = mx + b

y = 0x + b

y = 9

So, y = 9 is the equation

Rewrite the equation below in standard form.
enyata [817]
Well, the standard equation is in the form:

ax + bx = c (constant).

Thus, x and b must be isolated together on one side with the constant on the other. The equation which satisfies this is:

A. -2x + y = 5
