The train's rate: StartFraction 320 miles over 4 hours EndFraction 3. Write an equivalent rate with a denominator of 1. 4. Unit rate:

Step-by-step explanation:

Given

Solving (1): Determine the rate.

Rate, in this case is:

Solving (2): Simplify the denominator to 1

Divide numerator and denominator by 4

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
