2x9= 18
18×-6= -108
Your answer is 108.
To do this you want to divide 110 by 5 to get 22. Now you want to multiply 3 by 22. That means the caterer need 66 pounds of tomatoes.
Slope formula;
m = y2 - y1/ x2 - x1 (-2, -1), (3, 4)
m = 4 - (-1)/ 3 - (-2)
m = 5/5
m = 1
the slope is 1.
hope this helps, God bless!
