From the problem,
we have a y-intercept of -7 and a slope of 7.
Note that the slope is also represented by rise divided by run
So,
[tex]\text{slope}=\frac{\text{rise}}{\text{run}}=\frac{7}{1}[/tex]From the y-intercept, we need to go 7 units upward (rise) and 1 unit to the right (run).
Plot the y-intercept (0, -7)
