What is the equation of the line that has a slope of 4 and passes through then point (3,-10)?
Fynjy0 [20]
<h3>♫ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Substitute the x and y values into the equation:

y = mx + c

'm' is the slope, which we know is 4

-10 = 4(3) + c

- 10 = 12 + c

c = -22

The equation is y = 4x -22
