Answer:
Step-by-step explanation:
(-4,-8)...x = -4 and y = -8
slope = 3/2
in y = mx + b form, the m is ur slope
now sub ur info into y = mx + b......we need to find b, the y intercept
y = mx + b
-8 = 3/2(-4) + b
-8 = -6 + b
-8 + 6 = b
-2 = b
so ur equation is : y = 3/2x - 2.....but u need it in another form
y = 3/2x - 2.....subtract 3/2x from both sides
-3/2x + y = -2 ....then u can multiply by -2 and get 3x - 2y = 4....just in case u dont want fractions
D. The fourth choice is correct.
