Answer:
and do not lie on the line
Step-by-step explanation:
Given
Required
Determine which points that are not on the line
First, we need to determine the slope (m) of the line:
Where
So;
Next, we determine the line equation using:
Where
becomes
To determine which point is on the line, we simply plug in the values of x to in the equation check.
For
and
Substitute 4 for x and 2 for y in
<em>This point is on the graph</em>

Substitute 4 for x and 3 for y in
<em>This point is not on the graph</em>

2y=-4x+10
y=2/-4x+2/10
y=-2x+5
Average speed of cyclist = x
average speed of car = 3x
x = 225/5
x = 45km/h
3x = 3(45)
3x = 135km/h
average speed of cyclist = 45km/h
average speed of car = 135km/h
Answer:
Answer is the first choice.
Step-by-step explanation:
A logarithmic graph is the opposite of an exponential growth graph, so the first option is the only one that fits. Just took the test and the first choice is correct.
