Which equation represents a line that is perpendicular to line l on the graph below?

y= -1/2x + 3

Step-by-step explanation:

A line perpendicular will have the reciprocal slope.

First you need to find the slope of the line given.

m= rise/ run

m= -2

Now flip for the reciprocal.

The perpendicular line will have a slope of -1/2

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

50
