**y=x+2
when x=0,y=2; A(0,2)
when x=1,y=3; B(1,3)
**y=-x+8
when x=0,y=8; C(0,8)
when x=5,y=-3; D(5,-3)
The solution from the graph is S(2,4).
I would just try to identify the pattern. First, for the cups column, if the amount increases by 5 each time, then the missing box must be 5 less than 10 or 5
The, for the servings column, you can test to find the pattern. If you were to guess the pattern is 3, when you check, you would see that the boxes are 6 and 9 because then it increases by 3 each time
Hope this helps
Use the slope formula.
Y2 - Y1 / X2 - X1
(3,1) (6,-5)
-5 - 1 / 6 - 3
-6 / 3
slope = -2
