Arectangle is graphed on the coordinate grid. which represents the equation of a side that is perpendicular to side k

a. y=1/4x-10
b. y=-1/4x-10
c. y=4x+24
d. y=4x-10

B.

Step-by-step explanation:

Given rectangle with sides J,K,L and M.

We need to find equation of sides that are perpendicular to side K.

For a rectangle adjacent sides are perpendicular to each other.

For side K, the adjacent sides are J and L. Hence, sides J and L are perpendicular to side L.

Finding equation of side J.

Points: (-5,4) and (3,2)

Slope of line

where and are points on the line.

Thus

Simplifying fraction.

Using point-slope equation to find equation of the line.

Using point (-5,4)

Using distribution

Adding 4 to both sides.

Taking LCD to add fraction.

Equation of side J.

Finding equation of side L.

Points: (-8,-8) and (0,-10)

Slope of line

where and are points on the line.

Thus

Simplifying fraction.

Using point-slope equation to find equation of the line.

Using point (0,-10)

Subtracting both sides by 10.

Equation of side L.

The equation of side perpendicular to side K is represented by

step-by-step explanation:

what was your answer?

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.
