Answer:
y = 3
Step-by-step explanation:
The equation of a line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is any point on the line
Get the slope
m = y2-y1/x2-x1
m = 3-3/-4-(-7)
m = 0/-4+7
m = 0/3
m = 0
Substitute the point (-7, 3) and m = 0 into the formula;
y - 3 = 0(x-(-7))
y - 3 = 0(0+7)
y - 3 = 0
y = 0+3
y = 3
Hence the required equation of the line is y = 3
