If <span>y = –4x – 7, the x-intercept is found by setting y=0 and solving for x:
</span><span>0 = –4x – 7 => 4x = -7, or x = -7/4 The x-intercept is (-7/4, 0).
</span><span>The y-intercept is found by setting x = 0 and reading off the value of y:
y = –4x – 7 => y = 0 - 7, or y = -7. The y-intercept is (0, -7).</span>
Since we know the x and y, you would divide 480 by 15 and 32 miles per hour. Then you would multiply 7.2 by 32 and get 230.4. Your trying to find with wind and against wind so just times that by two and get 460.8. I think
