EXPLANATION

Given the dot (-3,2) and the slope -2, we know that the generic equation of a line is:

y = mx + b

Replacing the given data in the equation:

2 = -2*(-3) + b

Multiplying terms:

2 = 6 + b

Subtracting -6 to both sides:

2-6 = b

Switching:

b = -4

Now, we have that b= -4

Then, replacing this on the equation:

y = -2x -4

Answer: the equation that represents the line that contanis the point (-3,2) with a slope of -2 is ------> y = -2x -4
