The points given in the table lie on a line. Find the slope of each line.

Answers

Answer:

-2.5

Step-by-step explanation:

The slope of a line can be found by dividing the rise over the run between two points. The rise is the difference between the y-values, and the run is the difference between the x-values. For both, the value with the greater x-value comes first as you are seeing how much it has changed from the first value to the the other.

Let's use the first two points to find the slope: (0,9), (2,4)

(2,4) has the greater x-value, so the rise between the points would be -5, as 4 - 9 = -5

The run would be 2, as 2-0 = 2.

Therefore the slope would be: -5/2 = -2.5

Answer:

Since this is a proportional relationship,

We know that the number which are proportional are a multiple of each other

the number which we can multiply one of the numbers to get the other number is the constant of proportionality

we could check for proportionality by using the following formula:

p1 / s1 = p2/s2 = p3/s3 = p4/s4  if they were equal, we can say that the relation is proportional

The value of any of the above values, p1/s1 , p2/s2 , p3/s3 , p4/s4 is the constant of proportionality

Therefore, the constant of proportionality = 20 / 5 = 4

Answer:

Since this is a proportional relationship,

We know that the number which are proportional are a multiple of each other

Gamal spent $12.50 at the book store. The difference between the amount he spent at the video game store and the amount he spent at the book store was $17. The equation d minus 12.50 = 17 can be used to represent this situation, where d is the amount Gamal spent at the video game store. Which equation is an equivalent equation that can be used to find the amount Gamal spent at the video game store?
d = 17 minus 12.50
d = 17 + 12.50
d minus 12.50 = negative 17
d + 12.50 = 17

Answers

Answer:

choice 2

Step-by-step explanation:

d - 12.50 = 17

d > 17 > 12.50

d = 17 + 12.50

Answer:

d = 17 + 12.50
