One meaning of a 'linear' equation is that if you draw the graph
of the equation, the graph will be a straight line.
That's an easy way to test the equation . . . find 3 points on the
graph, and see whether they're all in a straight line.
This equation is y = 4 / x .
To find a point on the graph, just pick any number for 'x',
and figure out the value of 'y' that goes with it.
Do that 3 times, and you've got 3 points on the graph.
Here ... I'll do 3 quick points:
Point-A: x = 1 y = 4 / 1 = 4
Point-B: x = 2 y = 4 / 2 = 2
Point-C: x = 4 y = 4 / 4 = 1
Look at this:
Slope of the line from point-A to point-B
= (change in 'y') / (change in 'x') = -2 .
Slope of the line from point-B to point-C
= (change in 'y') / (change in 'x') = -1/2 .
The two pieces of line from A-B and from B-C don't even have
the same slope, so they're not pieces of the same straight line !
So my points A, B, and C are NOT in a straight line.
So the equation is NOT linear.
Try it again with three points of your own.
Answer:
(1, 0.5)
Step-by-step explanation:
From the graph attached,
x-values are representing the number of games downloaded,
y - values are representing the total cost.
Unit rate means rate of 1 game downloaded.
If we represent this in terms of coordinates,
x- value (game downloaded) = 1
y - value (price of one game download) = $0.5
Therefore, point (1, 0.5) will represent the unit rate.
Option (2) on the top row will be the answer.
Answer:
x=2
Step-by-step explanation:
3x+2=8
<em>Subtract 2 from both sides</em>
3x=6
<em>Divide both sides by 3</em>
x=2
Step-by-step explanation:
Sn=n/2(2a+(n-1)d). n=20
S20= 20/2 (2x5+(20-1)3 a=5
S20=10(10+57). d=8-5=3
S20=10x67
S20= 670
Hope this helps you
have a great day
