Answer:
y - 5 = -2(x-4)
Step-by-step explanation:
The equation of a line in point-slope form is ex pressed as;
y-y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line;
Given;
m = -2
(x0, y0) = (4,5)
Substitute the given values into the formula above;
y - 5 = -2(x-4)
Hence the point slope form of the equation is y - 5 = -2(x-4)
