Needing guidance and help with how to set up this problem and how to get the answer
1/5x + 1/10y = 2/5.
The directions say to graph the linear equations using intercepts.
Any help would be greatly appreciated!
Hello, smanfree!
It is very simple.
1) Rewrite your equation as 1/10y = -1/5x + 2/5.
2) Multiply both sides by 10 to eliminate denominators: y = -2x + 4.
3) To get the intercept value in "y" axis, substitute x = 0 into the last equation.
You will get y = 4.
Hence, the point A = (0, 4) lies in your straight line (see Figure 1).
4) To get the intercept value in "x" axis, substitute y = 0 into the last equation.
You will get -2x + 4 = 0. It gives you will x = 2.
Hence, the point B = (2, 0) lies in your straight line (see Figure 1).
5) Now draw the straight line through the points A and B (Figure 1).

It is what you need.
Good luck.
