Answer:
the unit rate in ounces of icing per cake=40 4/5
Answer:
y= -2/3x - 2
Step-by-step explanation:
So, the easiest thing to find first is your y-intercept, or the point in which the line crosses the y-axis. In this graph, the y intercept would be -2. Now, we can find the slope. One way to find the slope is to start at a point and count the numbers it rises and then the number it runs. Or, you can choose two points, like (0,-2) and (3,-4) and use the formula for slope, (y2-y1) / (x2-x1). Plug those numbers in and get (-4 minus -2)/ (3 minus 0), which would give you -2/3.
It would be: 39/40 * 100 = 3900/40 = 97.5%
