Answer: Slope of the line given in the table: m = - 0.25

Y-intercept of the line given in the table: b = -4

Slope of the line given by the equation: m = 1.5

Y-intercept of the line given by the equation: b = 1

Step-by-step explanation: <u>Slope</u> of an equation is an indication of the steepness and direction of a linear graph. It is denoted as m and it can be calculated as:

m = \frac{y_{2} - y_{1}  }{x_{2} - x_{1} }

Another way of determining the slope is as the form:

y = mx+b

<u>For the table</u>:

As in the table there are only points:

m = \frac{-3 + 2.5}{-4+6}

m = - 0.25

<u>For the function</u>:

The function is:

y = 3/2x + 1

m = 3/2

m = 1.5

<u>Y-intercept</u> is where the linear function crosses the y-axis, or when x=0. It can also be represented by the letter b.

<u>For the table</u>:

y = mx + b

According to the table, when y = -2.5, x = -6

-2.5 = - 0.25. (-6) + b

b = -2.5 - 1.5

b = -4

<u>For the function:</u>

y = 1.5x + 1

b = 1

In conclusion:

  • For the table: m = - 0.25 b = - 4
  • For the equation: m = 1.5 b = 1

Answer:

Find the slope and y-intercept for the two linear functions.

A 2-column table with 5 rows. Column 1 is labeled x with entries negative 6, negative 4, 2, 5, 9. Column 2 is labeled y with entries negative 2.5, negative 3, negative 4.5, negative 5.25, and negative 6.25. y = three-halves x + 1.

Identify the slope of the line given in the table:  

✔ -1/4

Identify the y-intercept of the line given in the table:

✔ -4

Identify the slope of the line given by the equation:

✔ 3/2

Identify the y-intercept of the line given by the equation:  

✔ 1

Step-by-step explanation:

Answer:

1: $92000 2: 52000 + 4000t= current salary

Step-by-step explanation:

1: simple arithmetic, 52000 + 4000(10)=92000

2: equation is formed as InitialSalary + 4000*(years at company) = New Salary

or with other variables, 52000+4000*t=N

Mumz [18]

Answer:

A

Step-by-step explanation:

x  |  y

0    0

1     4

2    n  -> 8

3    12

I've rewritten the x-y table so it's easier to read.

Take a point: 2,8. 2 times 4 is 8.

Take another point: 3,12. 3 times 4 is 12.

Ooh, looks like we have a pattern! After testing all the points (which you should always do in case there's an outlier) each x is multiplied by 4 to get the y. The formula for this is <u>y=kx,</u> where k is the constant of proportionality. So the equation is <u>y=4x.</u> This means x and y are directly proportional.

(They would be inversely proportional if in the form y=k/x; jointly proportional if they were in the form z=kxy, and nonproportional if there was no relationship at all.)
