PLEASE HELP ITS 7TH GRADE MATH PLEASE OMG HELO ILL GIVE BRAINLIEST PLEASE OMG PLEASE

Average speed, v = 1.66 km/h

Explanation:

It is given that, Ian walks 2 km to his best friend’s house, then walks 0.5 km to the library. He then makes a 2.5 km walk home.

Total time taken in the entire walk, t = 3 hours

We need to find the average speed of the Ian during his journey.

Total distance covered is,

Average velocity,

So, the average speed during the entire journey is 1.66 km/h. Hence, this is the required solution.

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.
