You go up 4 times and go to the left 2 times so the slope would be 4/-2
Exchange rate L 1 = $ 1.5542
Mary has $ 135
Pounds that Mary exchanged 135/1.5542
= L 86.8614 = L 87
I think it's a pattern, so x would be 3 and y would be 5 for the first one
x would be 20 for the second
and i dont even do word problems so...
It can be x = 3 and x = -15
