Answer

Both lines have a slope of 5. However, the two lines have different intercepts (both y-intercepts and x-intercepts). The blue line crosses the x-axis and the y-axis at $(0,0)$. The red line has an x-intercept at $x=-.8$ and has a y-intercept at $y=4$.

Work Step by Step

The graph was created using graphing software. Blue line: $y=5x$ Red line: $y=5x+4$
