Write the equation of the line whose slope and the point through which it passes are given. Express the equation in point-slope form.
(4,0) and slope m=-7

Step-by-step explanation:

Equation of a line

The point-slope form of the equation of a line is:

Where m is the slope and (h,k) is a point through which the line passes.

The line passes through the point (4,0) and has a slope of -7. The equation of the line is:

This is the point-slope form of the line.

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
