I start at 5,6 and move 4 units down what will i end up with

5,2

Step-by-step explanation:

since you're moving down the y-axis you will subtract 4 from 6 because 6 is on the y-axis

5 stays the same since you're not moving on the x-axis

(5,2)

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
