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

Answer:
a length of a cd is 6 inches
Step-by-step explanation:
Answer:
A is correct. This line has a negative slope meaning B and D are incorect.
If we count from 0, 3 (y intercept) to the next point on the line -3, 5 we see that the slope is -2/3
therefore A is correct
