Find the equation in slope-intercept form that descrives a line through (4,-2) with slope -3 a. y = -3x - 2 b. y = -3 x + 4 c. y = -3x + 10 d. y = -3x

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

So far we know the slope and can plug that into the equation like so...

y = -3x + b

Now we must find b

To do that you must plug in the point the line goes through in the x and y of the equation.

(4, -2)

-2 = -3(4) + b

-2 = -12 + b

10 = b

y = -3x + 10

Hope this helped!
