In your notebook, set up the following addition using a vertical format and find the sum of the given polynomials.
a - b + c, b - c + d, and c - d + e

If you set up the addition using a vertical format and find the sum of  the given polynomials, the answer would be: a + c + e

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
