Answer:
y= x-3
Step-by-step explanation:
The points are ;(0, -3), (5,2), (7,4), (10,7).
Plot the coordinates on a graph tool to visualize the graph
Select two points to find the slope ; take point (5,2) and (10,7)
m=Δy/Δx
Δy = 7-2=5
Δx=10-5 = 5
m=5/5 =1
The equation of the graph will be;
m= Δy/Δx
1=y-4/x-7
x-7 = y-4
x-7+4=y
x-3=y
y= x-3
Answer:
Option A.
Step-by-step explanation:
Consider the below figure attached with this question.
Scenario 1 represented by the graph.
From the graph it is clear that the line passes through the points (1,60) and (2,120).
Slope of the line is
The slope of line is 60. It means the speed is 60 miles per hour.
Scenario 2 defined by the equation,
If an equation defined as , then m is slope and b is y-intercept.
The slope of line is 50. It means the speed is 50 miles per hour.
The slope of Scenario 1 is greater than slope of Scenario 2. So, the Scenario 1 shows the greater speed.
Hence, the correct option is A.
