Answer: y + 1 = 2/5(x - 2), or y = 2/5x - 9/5

Step-by-step explanation:

for this you'll need point-slope form, which is:

y - y1 = m(x - x1)

m = slope

the slope is 2/5, because parallel lines have the same slope.

plug values in:

y - (-1) = 2/5(x - 2)

y + 1 = 2/5(x - 2)

if you want this in mx + b form:

y + 1 = 2/5(x - 2)

y + 1 = 2/5x - 4/5

y = 2/5x - 9/5
