Use (y2-y1)/(x2-x1)
(-1-5)/(0-3)
= -6/-3
= 2 the slope is 2
Amplitude is 3
Horizantal Shift 3 units to the left
Vertical Shift of 2 units up
Domain is [-1,1]
Range is [-1,5]
To be able to find the value of X, we have to cross multiply the two fractions then solve the equation.
As so,
6/4 = 15/x
Cross Multiply:
6 x X = 6x
4 x 15 = 60
We cross multiplied, now we can set up the equation:
6x = 60
Simplify: (Get X by itself)
Divide 6 on each side
6 / 6x = 60 / 6
x = 60 / 6
x = 10
Now we have the total of X! To check our answer, we can substitute X for 10 in the original equation.
As so:
6/4 = 15/10
6/4 = 1.5
15/10 = 1.5
Correct! Our answer is X = 10!

Answer:
90 miles.
Step-by-step explanation:
Knowing that an inch is equal to 40 miles you can take 40 and multiply it by 2 1/4, thus getting 90. Or, you can break it down. 2 times 40 equals 80. This leaves 1/4 inch left to figure out. If you divide 40 by 4 (figuring out a fourth) you would get 10. Add 80 and 10 and you would have 90 miles.
