Answer:
The equation of the line is y = 2
Explanation:
To find this, first start by using the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (2 - 2)/(5 - 1)
m = 0/4
m = 0
Now that we have the slope of 0, we can use point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = 0(x - 1)
y - 2 = 0
y = 2
