Inverse Variation is shown through the formula y=k/x
plug in the given values and solve for k: 3=k/5 so k=15
Answer: y=15/x
Answer:
y = 2x
Step-by-step explanation:
Formula is y = mx + b
m is slope
slope = (4 - -2) / (2 - -1) = 6 / 3 = 2
Now equation is y = 2x + b
To find b, substitute one of the coordinates in the equation. Let's use (2,4)
y = 2x + b
4 = 2(2) + b
b = 0
So equation is y = 2x
Answer:
25× 1/10 = 5/2
Step-by-step explanation:
5/2 or 2.5 lies between 2 and 3
Answer:
There are no options, so i will answer in a general way.
In a function:
y = f(x)
The output is y, and the input is x, and the ordered pair is written as (x, y)
In this case, we have the function:
y = -7*x + 6
Then we need to have different inputs and then find the outputs for each.
For example, if x = 1.
y = -7*1 + 6 = -1
Then we have the ordered pair (1, - 1)
if x = 0
y = -7*0 + 6 = 6
then we have the ordered pair (0, 6)
The general ordered pair is written as:
(x, y = -7*x + 6)
or:
(x, -7*x + 6)
Where you only need to replace the value of x.
