1. distributivity of the multiplication (a+b)(c-d)=a(c-d)+b(c-d)
2. the same
3. comutativity of the multiplication a*b=b*a
4. we give common factor xy: -5xy+2xy=xy(-5+2)=-3xy
We have the equation y=mx+b. Here, m is multiplied by x and represents the slope in our line, or its speed. The b here represents the starting point. First, since we start at the starting line, b is 0 (since we start from 0). Next, since our speed is 0.5, we multiply x by 0.5 to get 0.5x=y

W/-5 / 17 = -3
Multiply 17 on both sides
W/-5 = -51
Multiply 5 on both sides
Final Answer: 255
