Jessica is selling books during the summer to earn money for college. She earns a commission on each sale but her own expenses. After a month of driving from neighborhood to neighborhood and walking door to door, she figures out that her weekly earnings are approximately a linear function of the number she knocks on.
She writes the equation of the function likes this: E(x)=7x-25, where x is the number of door she knocks on during the week and E(x) is her earning for the week in dollars. Which w=of the following are reasonable interpretations of the y intercept of Jessica's function?

every 5 customers that walk in, only 2 buy popcorn.

step-by-step explanation:

basically 2/5.

brainliest would be appreciated.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
