The graph was created using the function y=-3x+8 which shows that 8 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=-3(0)+8 which equals 8. x =1, leads to y=-3(1)+8 which is 5. Another easier to way graph this would be moving down by 3 units on the graph when you moved across by 1 as the slope of the graph is -3. If you wanted to move to the negative x axis, you would go up 3 and move to the left by 1.
