Aparking lot began with two times as many spaces in a row as rows. after being expanded, 7 more rows were added and 9 more spaces in each row. the maximum number of spaces that the parking lot will hold is 582. if r represents the original number of rows, which of the following represents this situation?

a.
2r2 + 23r > 645

b.
2r2 + 63 > 582

c.
2r2 + 23r + 63 < 582

d.
2r2 < 645

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

hope that .

do you confirm there was a mistake in the question?
