First, you need to change it from standard form to slope-intercept form. To do this, you have to add 3x to both sides. Now that y is by itself, divide by 5 on both sides. Your equation should now be y=3x+3. Then, graph the points. Your x-intercept should be at (-5,0) and your y- intercept should be at (0,3).

Thanks.
The answer is 27.1052631579 or 27.1 if you rounded "m" to .10
speed is 45 miles per hour. 135/45=3, so the answer is 3hours (A)
