Question 771575: Could you explain how to solve this problem? It is supposed to plot 2 points on a coordinate graph. Here it is(8/3 and 80/3 are fractions, x is a variable not a multiplication sign, all the variables are undefined);
y = 8/3 x + 80/3 , 10 ≤ x ≤ 13
Answer by josgarithmetic(39617)   (Show Source):
You can put this solution on YOUR website! You mean this:
 and 
The two points to plot are (0, 80/3), and for convenience, you can pick any x value and find corresponding y value, and then draw a line. I suggest picking something like x=10, and find y, and plot this point. With the line drawn as described, you can simply read the points desired from the graph between x from 10 to 13.
Note, slope is  , and y intercept is  , so you can use that information to plot points to help draw the line.
