A tile store charges $350.00 to install 100 square feet of tile. Assuming they charge the same rate per square foot regardless of the amount of tile installed, how much would they charge to install 510 square feet of tile?

Translate to a proportion: $
=
x
square feet
square feet

They would charge
to install 510 square feet of tile.

The unit price for installation per square foot of tile is
.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2
