The equation of a line in point slope form is expressed according to the formula;
y-y0 = m(x-x0)
- m is the slope of the line
- (x0, y0) is any point on the line
Given the following parameters
m = -3
(x0, y0) = (-4, 1)
Substitute into the formula above will givee;
y - 1 = -4(x+4)
y -1 = -4x - 16
y = -4x - 15
Next is to plot the graph of the line y = -4x - 15 on the coordinate plane as shown:
