Answer:
Look below.
Sorry if the graph's aren't good.
Step-by-step explanation:
13) I'll attach a pic of my graphs:
Slope intercept form is y = mx + b
y = 2x + 1
m = 2
b = 1
14) y = 3/ 5x - 5
m = 3/5
b = -5
15) y = 1/4x - 8
m = 1/4
b = -8
3 cups because you have to add 1/4 for every batch she is making
Answer:
Step-by-step explanation:
Multiplying or dividing an inequality by a negative number requires that the inequality symbol be reversed.
__
To solve this inequality, we can divide by the coefficient of x, which is -8. Dividing by -8 means we need to reverse the inequality symbol.

<em>Additional comment</em>
Actually, applying any function that has a negative slope means the ordering is reversed. That is the more general case.
Here, we're specifically concerned with division by a negative number. You can see the effect on the ordering relation by considering ...
- -2 < 1
- 2 > -1 . . . . divide both sides by -1
