Answer:


\displaystyle y = 2x + 2

Explanation:

Starting from the y-intercept of
\displaystyle [0, 2],travel south two units, then west one unit to the endpoint AND x-intercept of
\displaystyle [-1, 0].Doing so will give you the rate of change of 2:


\displaystyle (-y_1 + y_2)/(-x_1 + x_2) = m \\ \\ (-2 ± 0)/(0 - 1) = m \hookrightarrow (-2)/(-1) = m \\ \\ 2 = m

With all the above information, you arrive at the equation of the line.

I am joyous to assist you at any time.
