Answer

The graph was created using the function y=0.2x-7 which shows that -7 is the y-intercept. The graph is in the screenshot.

Work Step by Step

The graph was created by plugging in the x values into the equation. So when x is 0, y=0.2(0)-7 which equals -7. x =1, leads to y=0.2(1)-7 which is -6.8. Another easier to way graph this would be rising by 0.2 units on the graph when you moved across by 1 as the slope of the graph is 0.2. If you wanted to move to the negative x axis, you would go down 0.2 and move to the left by 1.
