Find an equation whose line is perpendicular
to the line on the graph.
y =2x+2
y = 2x + 7
y=-1/2x-7
y=1/2x+1

First, we must find the slope of the graphed line. We can use the formula , where and are known points on the line.

Plug in the values.

Subtract.

Simplify.

To find the slope of the perpendicular line, we must find the opposite inverse slope. This means we first need to multiply it by , then we need to swap the numerator and denominator.

Now, swap the numerator and denominator. The numerator is , and the denominator is by default.

The only answer choice with a slope of is

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.
