Hello, hope you are having a nice day.
First, let's make sure the equation of our line is written in slope-intercept form.
Slope-Intercept Form looks like this:
y=mx+b
Where
m is the slope of the line
b is the y-intercept (where the graph touches the y-axis)
For this line, 7 is the slope, and -8 is the y-intercept form.
Hope it helps. I am always glad to help. Please ask me if you have any queries.
