Answer
The graph was created using the function y=6x+3 which shows that 3 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=6(0)+3 which equals 3. x =1, leads to y=6(1)+3 which is 9.
Another easier to way graph this would be rising by 6 units on the graph when you moved across by 1 as the slope of the graph is 6. If you wanted to move to the negative x axis, you would go down 6 and move to the left by 1.
