Did i do 8 and 9 correctly solve for m dir y- intercept

8)

looks good, so the equation in slope-intercept form is

y = 2x + 0

m = 2, y-intercept  is +0 or namely (0,0)

9)

if we multiply by -1 at -y = -4x + 4, we'd get y = 4x - 4.

m = 4, y-intercept at -4, namely (0, -4).

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
