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

thats not a system of equations, that is a solution

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
