Original equation: y = 2x + 7
which equation will shift the graph of the original equation 2 units up?

a) y = 2x + 9
b) y = 4x + 7
c) y = 2x + 2
d) y = 2x - 2

multiple all that

step-by-step explanation:

27×17

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
