Question

Write an equation of the line that passes through (-1,3) and has a slope of 2.​

Answer 1

Answer: y = -2x + 1.

Explanation:

From (-1, 3) follow the line to go 1 to the right and 2 down (because the slope is -2). That takes you to (0, 1). So the y-intercept is 1 and the equation is y = -2x + 1.
