Answer:
y = 3x + 3
Step-by-step explanation:
Y intercept is 3 so that's at the end of the equation. Input the points and that equation fits.
Answer:
Ashley can travel 10 miles with $10.
Step-by-step explanation:
This problem can be modeled with a linear equation:
where y is the total cost and x is the number of miles.
Given a y of 10, you can plug that in and solve for x:
Ashley can travel 9 miles with $10. You can check that either by solving the equation in the other direction, or doing it logically like this:
If she can travel 9 miles at $0.75 per mile, that's $6.75.
$6.75 + the flat rate of $3.25 is $10, so it works.
Answer:
A. -4
Step-by-step explanation:
Perpendicular lines have negative slopes
so you would have to flip the fraction and change the sign
so 1/4x = -4/1x or -4x
