Answer:
On a graph you would start at the point (0,7) as 7 is the y-intercept. A slope of 7 can be translated to a slope of 7/1. This means you would go up 7 points from the y-intercept then move to the right one. You can keep doing that going up. You would also go down 7 to the left one while also starting from the y-intercept. This would make a line.
To see this visually on a calculator graph, you can plug y=7x+7 into a calculator.
