Answer: The equation is y = 2x -3

Explanation:

Use the slope intercept formula (y=mx+b) and input the slope plus the x and y coordinate to solve for b(the y(the intercept) and write the equation.

y = mx + b m is the slope and be again is the y intercept.

-1 = 2(1) + b

-1 = 2 + b

-2 -2

b = -3

Therefore the equation is, y = 2x -3
