Sam is walking to joe’s house at a rate of 2 miles per hour. joe left his house at the same time and is walking at a rate of 1.5 miles per hour. if sam and joe live 7 miles apart, how long will it take for sam and joe to meet?

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.

answer: 1 + 1 = 11
