Answer:

The number of Pencils purchased and the cost of pencils represents a proportional relationship.

Step-by-step explanation:

As we know that proportional relationships between two variables have equivalent ratios.

For example,

3/12 = 9/36 is a TRUE proportions because both fractions reduces to 1/4, and because  12 × 9 = 3 × 36.

As our problem suggests whether the number of Pencils purchased and the cost of pencils represent a proportional relationship?

Given

  • Pencils $0.25 each

It means ach pencil costs $0.25.

So

  • If Sarah buys 1 pencil it would cost = $0.25
  • If Sarah buys 2 pencils it would cost = $0.5
  • If Sarah buys 3 pencils it would cost = $0.75
  • If Sarah buys 4 pencils it would cost = $1

Lets make a table:

No of Pencils Purchased               Cost

                  1                                   $0.25

                  2                                   $0.5

                  3                                   $0.75

                  4                                   $1

so

Cost/No of Pencils Purchased = 0.25/1 = 0.5/2 = 0.75/3 = 1/4

So cost per pencil = 0.25 : 1

Since all of the ratios are equivalent, this table is a proportional relationship.

Therefore, the number of Pencils purchased and the cost of pencils represents a proportional relationship.

The points (1,-10) and (r,2) fall on a line with a slope of 2 what is the value of r.
zalisa [80]

The value of r in the given coordinates with their slope is; r = 7

How to find the Slope of a Line?

The formula for slope of a line passing through 2 points is;

m = (y2 - y1)/(x2 - x1)

We are given the coordinates as;

(1,-10) and (r,2)

The slope of the line passing through this coordinates is 2. Thus;

(2 + 10)/(r - 1) = 2

12 = 2r - 2

2r = 14

r = 14/2

r = 7

If a line has a slope of 1/2 and a y-intercept of -6, what is the x-coordinate if the y-coordinate is 4
ivanzaharov [21]

Answer:

X=20. Our x coordinate is 20.

Step-by-step explanation:

Based from the given slope of 1/2 and a y-intercept of -6, our equation of a line is y=x/2 -6. To remove the fraction we can multiply the equation by 2 to get 2y=x-12. Using this substitute the value of y coordinate 4.

2(4)= x-12

8+12 =x

X=20.
