Question

Passes through (3,-6), slope = 2

Answer 1

y = 2x - 12

Explanation:

y = 2x + c

-6 = 2(3) + c

c = -6 - 6 = -12

y = 2x - 12

Answer 2

y = 2x-12

Explanation:

The equation for a line in slope intercept form is

y = mx+b

where m is the slope and b is the y intercept

y = 2x+b

Substitute the point into the equation

-6 = 2(3) +b

-6 = 6+b

Subtract 6 from each side

-6-6 =6-6+b

-12 =b

y = 2x-12
