Answer:
$0.75
Step-by-step explanation:
dozen=12
12=$2.25
1=2.25/12
4=2.25/12*4
=$0.75
2.5 /10 = 10 / x
100 = 2.5x
40 =x
To find the slope in the graph you need to find two perfect points on the line then count how many times you went up which is the y over how many times you go right which is the x its called the rise/run. To find the slope in the equation use the formula y2-y1/x2-x1.
