5bridesmaids want to make  325   decorations for a wedding.  each decoration takes about  2 1/2minutes to make.  which response gives the best estimate for the amount of time each bridesmaid will spend making decorations?

Divide 325 by 5 to get the number of decorations that each bridesmaid makes. 
325 ÷ 5 = 65 
Multiply 65 by 2.5 because each takes 2 1/2 minutes to make. 
65 x 2.5 = 162.5 
162.5 minutes is equal to 2 hours and 42 1/2 minutes. 
Hope this helps!

There is no graph but what i can say is that 1 is the slope and that -2 is the y- intercept
