Which of the following is the equation of the line that has a slope of 3 and passes through the point (-2,6)

The equation is y= 3x + 12

Explanation: Slope(m) is the change in y divided by change in x. So:

m= (y - y')÷ (x - x'). From the coordinates you're given, x'= -2 and y'= 6. Therefore 3= (y-6)÷(x--2). If you cross multiply, you have y-6 = 3(x+2). That is y-6 = 3x + 6. So y= 3x+6+6. Then you have y= 3x +12.

I hope I was able to help.
