Question

Can someone answer the highlighted question!!! PLEASE

Answer 1

The equation in slope intercept form is:

$y=-3x+9$

A line parallel to this would have the same slope, which means our line that passes through the point (0,-4) has a slope of -3. We now have to plug in 0 as our x and -4 as our y in y=-3x+b so:

$-4=0x+b \implies \\ -4=b$

Our equation is then y=-3x-b
