Lana's bus is usually on time. but this week, she waited 18, 20, 35 ,19 and 35 mintues . estimate the total time she spent waiting for the bus. a.100 minutes b.120 minutes c. 130 minutes d.140 minutes me

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.
