The function has an intercept of -2 and y intercept of -2/3. Write an equation.

poizon [28]

Answer:

y= -1/3x - 2/3

Step-by-step explanation:

y- intercept is (0, -2/3) and the x intercept is (0, -2).

To find the slope of an equation, you do rise over run. To get from (0, -2/3) to (0, -2), you rise 2/3 and run -2. 2/3 divided by -2 is -1/3, that is where you get the slope from.
