The slope of the line is -2/3.
This is found by using the equation y2 - y1/x2 - x1. Filling in for each factor, you would have 1-3/1+2 (since subtracting a negative makes it positive). This will give you a final answer of -2/3.
Here is a graph of the full equation of the line.
I hope this helps!
To find the zero you must set each factor equal to zero and solve for for x like so...
Factor (x - 7)
x - 7 = 0
x = 7
Factor (x + 4)
x + 4 = 0
x = -4
Factor (3x - 2)
3x - 2 = 0
3x = 2
x = 
All the zeros are:
-4, , 7

Answer:
Here, 
denotes number of frosting flowers
Step-by-step explanation:
Let denotes number of frosting flowers.
Amount charged by baker for each batch of cupcakes = $30
Amount charged for each frosting flower = $0.09
So,
Amount charged for frosting flowers = 
Therefore,
Total cost of a batch of cupcakes with frosting flowers =
