-249/20 seems like the answer
Matt sold the most, figure out the percentages of each by diving the top number by the bottom number.
Please, in the future, post just one problem at a time.
Looking at Problem #1: The line intersects the y-axis at (0,-3) and intersects the x-axis at (1,-1). At least, this is what I see; your graph is small.
-3-[-1]
The slope of that line is then m = rise / run = ------------ = +2.
0 - 1
[change in y]
Slope = m = rise / run = --------------------
[change in x]
Answer: C. 6 1/6
Step-by-step explanation:
2 * -5 * -7 = -10 * -7 = 70
70 + 4 = 74
3 * 4 = 12
74/12 = 6 1/6
