Two planes just took off from Salt Lake City, UT. The first plane is traveling 3.5 times as fast as the second plane. After traveling in the same direction for 4.5 hours, they are 956.25 miles apart. What is the average speed of each plane? (Hint: Since they are traveling in the same direction, the distance between them will be the difference of their distances.)

15 points! write the slope-intercept form of the equation of the line through the given point with the given slope. use y-y = m(x-x) to solve. through (2,5) slope= undefined

Is the point (0, 8) on the x-axis or y-axis? how do you know?
