1. check all solutions of the equation: 5x(x - 2) = 0
a. 0
b. 2
c. -2
d. 5
2. factor by grouping: xy - 2y + 2x - 4
a. (x + 4)(y + 2)
b. (x - 2)(y + 2)
c. (x + y)(x - 2)
3. factor and solve the equation. 9x2 - 30x + 25 = 0
a. -5
b. -3/5
c. 5/3
d. 1

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

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
