The number of words maria typed directly varied with with the amount of time she spent typing. if she typed 275 words in 5 minutes how long would it take her to type 1,100 words?

20 minutes

Step-by-step explanation:

Given: The number of words Maria typed directly varied with with the amount of time she spent typing.

The formula of direct variation between two variables x and y is  given by :-

Let be the time taken by Maria to type 1,100 words, then

Hence, she type 1,100 words in 20 minutes.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
