I’m assuming you need to find the equation of the line?
Equation of line is written in the form y=mx+c where m is the slope and c is the y-intercept.
We know the slope is -4, so we have y=-4x+c.
To find c, we replace the given coordinates in the equation:
4=-4(-5)+c
4=20+c
c=-16
So, the equation of the line is
y = -4x -16
