Graph: y = 3x - 5<br> Plz help
nexus9112 [7]

Answer:

The equation, y=3x-5 is in y=mx+b format. The b, or -5 in this case, tells you what the y intercept is, or in this case, your starting point. This means your first point will be at (0,-5). The mx, or 3x in this case, tell us how much to move     up and how much to move sideways. 3x is equal to 3/1x and the 3/1 tells us the rise/run. Rise being how much to go up or down and run being how much to go to the left or right. So in 3x, the rise is 3 and the run is 1. So you will go 3 up on the y axis and 1 to the right on the x-axis. So your next point will be (1, -2) and the point after that will be (2, 1) and so on!

hope this helped!

We have been given that at the start of a year, company XYZ's stock is $40 per share. At the end, the company's stock is $60 per share. We are asked to find the percent increase.

We will use percent increase formula to solve our given problem.

\text{Percent increase}=\frac{\text{Final}-\text{Initial}}{\text{Initial}}\times 100\%

\text{Percent increase}=\frac{60-40}{40}\times 100\%

\text{Percent increase}=\frac{20}{40}\times 100\%

\text{Percent increase}=0.5\times 100\%

\text{Percent increase}=50\%

Therefore, the stock price's rate of return was 50%.
