Omar is hiring a painting company to paint the interior of his house. The table represents prices the painting company quoted Omar.


Write a two-variable linear equation to represent the total cost, c, given the square feet, s, of the house.

A: c=2.25s+1347.85

B: c=2.25s+2847.85

C: c=2.25s+4047.85

D: c=2.25s+7654.60

Answer :

The linear equation to represent the total cost c = 2.25s + 1,347.85.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

Using slope

slope= ( 5847. 75 - 4074 . 85)/( 2000- 1200)

slope= 1800 - 800

slope= 2.25

and, slope- intercept form

c - 4047.85 = 2.25 ( s- 1200)

c - 4047.85 = 2.25s - 2700

c = 2.25s - 2700 + 4047.85

c = 2.25s + 1,347.85

Hence, linear equation to represent the total cost c = 2.25s + 1,347.85.
