Please help and can you explain how you got it? Also what grade level is the work (6th, 7th or 8th)?

The equation of line p is y = -³/₂x + 3

Step-by-step explanation:

Let's first find the slope of the line.  That's equal to Δy/Δx:

(-3 - 6) / (4 - (-2))

= -9 / 6

= -3/2

With that, we can plug it in to the format:

Δy = sΔx, or (y - y1) = s(x - x1):

y - 6 = s(x - (-2))

y - 6 = (-3/2)(x + 2)

y = -3x / 2 - 3 + 6

y = -³/₂x + 3

the correct option is b
