Answer:
The equation of the line would be y = .5x + 2.5
Step-by-step explanation:
In order to find this, we must first find the slope of the equation.
m (slope) = (y2 - y1)/(x2 - x1)
m = (2 - 3)/(-1 - 1)
m = -1/-2
m = .5
Now that we have the slope, we can use either point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 3 = .5(x - 1)
y - 3 = .5x - .5
y = .5x + 2.5
