I’m not sure I only answer these for the points :)
Given equation is y=2x+7 and 
Let's simplify the 2nd equation
before we can start graph so that calculation will be easy

multiply both sides by 2 to cancel out fractions

y=2x+7
which is exactly same as the first equatoin so graph of both will be exactly same and solution will be infinitely many solutions.
y=2x+7 has y-intercept 7 so first point will be (0,7). Slope is 2 so rise 2 unit up then 1 right and graph the new point.
Answer: 18
Step-by-step explanation:
1/4 of 32 = 8

7 apples = $6.23
1 apple = 0.89
9.79 / 0.89 = 11
11 apples
Hello,
We can not divide by 0.
