Coach keller is having the last names of his players printed on their shirts! ?

Step-by-step explanation:

We are given the table representing the cost for the number of letters to be printed on shirts.

As, we know that slope is given by .

So, taking any two points ( x,y ) from the table say ( 15,7 ) and ( 20,8.25 ), we find the slope.

i.e.

i.e.

i.e.

i.e.

So, the slope is 0.25.

Now, we substitute the value of the slope and the point ( 15,7 ) into the equation y = mx + b.

i.e. 7 = 0.25 × 15 + b

i.e. b = 7 - 0.25 × 15

i.e. b = 7 - 3.75

i.e. b = 3.25

So, the y-intercept is 3.25

Hence, the linear equation is given by y = 0.25x + 3.25.

We know that the company charges a flat fee and also charges amount per letter.

Since, y = 0.25x + 3.25 is the total cost charged for the letters.

This gives us that, the slope 0.25 represents the charge per letter and the y-intercept 3.25 represents the flat fee charged.

step-by-step explanation:

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
