The graph represents the relationship between the minutes a phone is charged, m, and the percentage charged p. Which function can be used to determine the percent charged, p, after m minutes?

p=10m+43

p=10m+34

p=34m+10

p=43m+10

p= 10m+43 I hope this help let me know if it is right

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.
