Answer:
y-intercept (0, -3) and x-intercept (3/2, 0)
Step-by-step explanation:
y + 5 =2(x + 1)
y + 5 =2x + 2
subtract 5 from both side
y =2x -3
-3 is the y-intercept because in y=mx+b, b is the y-intercept and it always starts at 0.
To find the x-intercept, we need to plug in 0 for y in y =2x -3
0=2x -3
add 3 to both sides
2x=3
divide both sides by 2
x=3/2 and so the x-intercept is 3/2 and it always starts at 0.

Answer:
Lizzy's recipe is not a proportional relationship with the brownie recipe because of the difference in ratio.
Step-by-step explanation:
Brownie recipe:
Cocoa powder = 3 parts
Flour = 2 parts
Ratio of cocoa powder to flour = 3 : 2
Lizzy's recipe:
Cocoa powder = 1 cup
Flour = 1 cup
Ratio of cocoa powder to flour = 1 : 1
