Notice the table of values
when x = 2, y = -5
then "x" goes 2 units over to 4, and "y" moves over to 5, now from -5 to 5 is 10 units, so when "x" moved just 2 units, "y" went 10.
then "x" goes further down to 7, moving 3 units over,
and "y" goes further from 5 to 20? what the? it went 15 units.
so.... hmmm notice, is we do some quick splitting and instead check how much "y" is moving for every unit on "x".
notice, on 2 units of "x", "y" moved 10 units
and on 3 units of "x", "y" moved 15 units, like from 5 to 20.
so, "y" is really moving 5 units on every unit moved by "x", so the "rate of change" or slope is indeed constant, is 3 to 1 all the way.
Answer:
The answer is (6,4)
Step-by-step explanation:
Answer:
D) 15/12 and 5/4
Step-by-step explanation:
Because when you cross multiply the ratios
15*4 and 12*5
making both ratios a proportion
they both = 60
Answer:
143
Step-by-step explanation:
180 - 37 = 143.
We know this because y + 37 = 180
so we can does 180-37 to get our answer.
Answer: Rina is 
feet taller than Ryan.
Step-by-step explanation:
Given, the height of Rina = 
feet
The height of Ryan = 
feet
To find : How much taller is Rina than Ryan?
Clue : Rina is taller than Ryan.
For that , we need to check the difference of the height between Ryan and Rina
i.e. (height of Rina) - (height of Ryan)
Hence, Rina is feet taller than Ryan.
