Which ordered pair would form a proportional relationship with the point graphed below?

Which Ordered Pair Would Form A Proportional Relationship With The Point Graphed Below?

Answers

Answer 1

Answer:

-10, 20 because -20, 40 divided by 2 = -10, 20

Answer 2

The ordered pair that would form a proportional relationship with the point (-20, 40) is given as follows:

(15, -30).

What is a proportional relationship?

A proportional relationship is a relationship in which a constant ratio between the output variable and the input variable exists.

The equation that defines the proportional relationship is a linear function with slope k and intercept zero presented as follows:

y = kx.

The slope k is the constant of proportionality, representing the increase or decrease in the output variable y when the constant variable x is increased by one.

The constant for this problem is given as follows:

k = 40/-20

k = -2.

Hence the equation is:

y = -2x.

When x = 15, the numeric value of the equation is given as follows:

y = -2(15)

y = -30.

Hence the point is:

(15, -30).

A 6-pound bag of sugar costs $7.98. What is the unit price?

Answers

Answer:

1.33

Step-by-step explanation:

Lets start by making a quick equation:

Total cost is y, or 7.98, with the weight being 6 pounds. We are looking for the unit price, which will be our x.

7.98 = 6x

Divide 6 by both sides:

7.98 / 6 = 6x / 6

This gets rid of the 6 on the right, so we are left with:

1.33 = x

So the unit price is $1.33 per pound.

I hope this helps! :)

Y=1/2x+2
The original slope is 2/4 so simplify making 1/2

Answer:

Y = 1/2x + 2

Step-by-step explanation:

First you find (b) or the Y-intercept which is 2 (Y = mx + 2)

Then you do rise over run to find slope. Rise = 1. Run = 2. Slope (m) = 1/2

Now you have your answer Y = 1/2x + 2
