write a linear equation that represents the cost of buying t-shirts from shantay's shirts. identify the meaning of each variable in your equation.

Part 1)

Part 2)

Step-by-step explanation:

Part 1) Write a linear equation that represents the cost of buying t-shirts from Paula's printing.

Let

x ----> the number of t-shirts

y ----> the cost in dollars

step 1

Find the slope

The formula to calculate the slope between two points is equal to

take two points from the table

(2,23.5) and (4,25.5)

substitute in the formula

step 2

Find the equation of the line in point slope form

we have

substitute

Convert to slope intercept form

Part 2) Write a linear equation that represents the cost of buying t-shirts from Shantay's shirts.

Let

x ----> the number of t-shirts

y ----> the cost in dollars

step 1

Find the slope

The formula to calculate the slope between two points is equal to

take two points from the table

(2,20) and (4,22)

substitute in the formula

step 2

Find the equation of the line in point slope form

we have

substitute

Convert to slope intercept form

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
