PLEASE I NEED THIS DONE BY MIDNIGHT HELP
Khalid and Jesse took different overnight trains.
The graph shows the relationship between the total distance Khalid traveled and the time in hours.
The distance Jesse traveled after x hours is given by the equation y = 150x. Who, if anyone, traveled at a faster speed?
Use the drop-down menus to explain your answer.

Khalid’s rate is ____ miles per hour. Jesse’s rate is ____ miles per hour. So, ____ train traveled at a faster speed.

Answer:

Khalid’s rate is ___140_ miles per hour. Jesse’s rate is _150___ miles per hour. So, _Jesse’s___ train traveled at a faster speed.

Step-by-step explanation:

The general equation of a straight line is

y = mx + b

for y = 150x

We have the slope as 150

This is 150 miles/hour

This relates to Jesse’s train speed

for Khalid, we have his own speed obtainable from the graph

The speed is simply the slope of the graph

We proceed to select two points from the graph and find the slope

The points are; ((1,140) and (4,560)

Mathematically, the slope will be;

m = (y2-y1)/(x2-x1)

m = (560-140)/(4-1) = 420/3 = 140 miles per hour
