Write the equation of a line with the slope of 2, which contains the point (4,-8).

y = 2x-16

Step-by-step explanation:

To find a line when we know the slope and a point, we can use the point slope formula for a line

y-y1 = m(x-x1)  

where the point is (x1,y1) and the slope is m.  Substituting the known information in.

y--8 = 2 (x-4)

y+8 = 2(x-4)

We can manipulate this into slope intercept form by distributing the 2

y+8 = 2x-8

and subtracting 8 from each side

y+8-8 = 2x-8-8

y = 2x-16

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.
