I think its 10
Correct me if im wrong
But all u have to do is multiply 2.5 x 4=10
Not sure exactly what you mean, but heres the answers i got for this:
Exact form: 15/2
Decimal form: 7.5
The slope is -3/1 so to find other points, go to (2,-1) and go down 3, over 1.
The equations are 30+2x and 16+5x. i plug random numbers into x until you fint the correct answer. the answer is 5.
