Answer:
The equation would be y = -1/2x + 7/2
Step-by-step explanation:
To find the equation, we first need to use the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (2 - 4)/(3 - -1)
m = -2/4
m = -1/2
Now that we have that, we can use that and a point to find the full equation.
y - y1 = m(x - x1)
y - 2 = -1/2(x - 3)
y - 2 = -1/2x + 3/2
y = -1/2x + 7/2
