Can someone help me answer (b)? Thanks! :)

No

Step-by-step explanation:

Parallel lines have equal slopes.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - x + 3 ← is in slope- intercept form

with slope m = -

Calculate the slope m of the 2 points using the slope formula

m =

with (x₁, y₁ ) = (- 4, 7) and (x₂, y₂ ) = (8, 4)

m = = = -

Since slopes are not equal then the lines are not parallel.

b.) divide by -5.
