The graph was created using the function y=-1.8x-6 which shows that -6 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=-1.8(0)-6 which equals -6. x =1, leads to y=-1.8(1)-6 which is -7.8. Another easier to way graph this would be going down by -1.8 units on the graph when you moved across by 1 as the slope of the graph is -1.8. If you wanted to move to the negative x axis, you would go up by 1.8 and move to the left by 1.
