First thing you need to know is that the slope is equivalent to rise divided by run.
y-intercept is a point on the y-axis that the line will intersect.
From the problem, we have a y-intercept of -5
Plot the point (0, -15).
Next step is to plot the second point using the slope of -2
So the rise is -2 (we need to move 2 units downward since the sign is negative)
and the run is 1 (we need to move 1 unit to the right since the sign is positive)
The second point will be :
Then connect the two points with a straight line.
The graph will be :
