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.

it would be:

c.parallelogram.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
