Terry's investment of $2,200 in the stock market and $528 and 2 years find the simple interest rate for the investment

I don't know if this is correct but i think its 24%

For a 0.25 pfor b o.3pp (0.25+0.3)=0.28

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
