Which description best represents the equation 25x + 50 = y?

see the explanation

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

In this problem we have

This is the equation of a line in slope intercept form

so

Is a linear equation (the graph is a line)

The slope is positive and is equal to

The y-intercept is the point (0,50) (y-intercept is the value of y when the value of x is equal to zero)

The value of b is (y-coordinate of the y-intercept)

The x-intercept is the point (-2,0) (x-intercept is the value of x when the value of y is equal to zero)

The linear function is a increasing function (the slope is positive)

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
