#### Answer

The point of intersection is (-3,-11)

#### Work Step by Step

#1 $y=4x+1$ $Slope=m=\frac{4}{1}$ $y-intercept = b = 1$ To graph this function first plot 1 on y-axis then go up 4 and right 1. #2 $y=2x-5$ $Slope = m= \frac{2}{1}$ $y-intercept = b=-5$ To graph this function first plot -5 on y-axis then go up 2 and right 1. #3 The graph is-
