Write the equation of the line that passes through (-1, 8) and is parallel to the line that passes through (5, -1) and (2, -5).

Point point form for the line through (a,b) and (c,d) is

(c-a)(y-b) = (d-b)(x-a)

We don't care about the constant part, this is

(b-d)x + (c-a)y = some constant

(a,b)=(5,-1) and (c,d)=(2,-5)

(-1 - -5) x + (2 - 5)y = some constant

4x - 3y = some constant

We didn't bother to calculate to constant because the parallel through (-1,8) means we get a different constant, obviously

4x - 3y = 4(-1) - 3(8)

4x - 3y = -28

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
