Answer:
Step-by-step explanation:
Rate of change of x and y can be calculated using the following formula and using any two given pair of values from the table:
Rate of change =
Using (-12, 60) and (-6, 33).
Where,
Plug is the values
Rate of change =
Rate of change =
Simplify
Rate of change =
Rate of change =
First you simply have to substitute 2 in replace of all the a's, and -2 in replace of all of the b's
4((2)2+2(-2))
Then you want to follow the order of operations, PEMDAS (Parantheses-Exponent-Multiplication-Division-Addition-Subtraction), and multiply within the parantheses.
4(4+(-4))
Next you will add within the parantheses (So add the 4 and -4 together)
4(0)
Lastly multiply
0
Your answer is 0

Mx+b=y
subtract b from both sides
mx=y-b
divide m in both sides
x=(y-b)/m
