Question

Use the given information to write the equation of a line.

slope = -2 and passes through through (1,1)

Answer 1

y = -2x - 1

Explanation:

If you already know the slope. Just find out the y-intercept. Plug the coordinates into the equation.

y = mx + b

y = -2x + b

1 = -2(1) + b

1 = -2 + b

-1 = b
