Since 100% is the full amount, and it is 35% off you add 35 to the 100. So you get 1.35. You finally multiply by 207 and get 280.8

I want to learn how to solve a slope problem

mina [271]

The slope (or average rate of change) formula is: $m= \frac{ y_{2}- y_{1} }{ x_{2}- x_{1} }$ . It is easy to remember as "slope is easy and fun, rise over run" where the y-values of the 2 points would be the "rise" and the x-values of the 2 points would be the "run" So with two points, you label one point as $( x_{1}, y_{1})$ and the other as $( x_{2}, y_{2})$ . Then you insert these points into the slope formula (m represents slope). So, $m= \frac{6-1}{-3-5}$ where (-3,6) is x2 and y2 and (5,1) is x1 and y1. It would simplify to $m= \frac{5}{-8}$ .
