K. So, first add 24.95 and 35.99. You get 60.94 (Remember This!)Now you take 49.95 divided by 2. you should get: 24.975.add 24.975 with 60.94. You get 85.915take 85.915 and multiply it by 0.15. You get 12.88725. Subtract 85.915 by 12.88725. You should get 73.02775.Now multiply that by 0.045. you should get 3.28624875. Add that onto 73.02775, and you get 76.31399875.Round that to the nearest hundredth, and your done! (The answer is: 76.31!)

Answer:

Alright bear with me, this is gonna be a long one.

The Y INTERCEPT

So the y-intercept is going to be where the line intersects the Y-AXIS. The y-axis is the vertical part of the graph with the numbers on it.

So, for the first one, the line goes through the origin which means that that the y intercept is going to be (0,0)

The next one, the line intersects the y-axis at (0,1)

Here's a tip: the y-intercept will always have 0 as it's x coordinate.

The Slope

Alright, the slope of a vertical line can be found using an equation. Most typically people will describe the slope as RISE/RUN meaning how many units you move up "rise" and how many units you move horizontally "run" to touch the line. Of course, it's easier when you can identify points.

So to make this a little bit easier to understand, I will show you how to use the equation to find the slope.

$\frac{y2-y1}{x2-x1}$
