Ashley has walked 25% of the way home from school. If she has walked 200 meters so far, how long is her walk home from school?

800

Step-by-step explanation:25% of 800=200

800 divided by 4 =200

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
