Actually it would be 4 hours $60 because the question says he earned the same amount of money at both jobs. The only place on the graph where both jobs earned the same amount for the same amount of time is where they intersect at 4 hours and 60$
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:
Infinitely many solutions
Step-by-step explanation:
Solve y = 3x+1 for y
y = 3x+1
Substitute 3x+1 for y in -6x+2y = 2
−6x+2y = 2
−6x+2(3x+1) = 2
2=2
2+−2=2+−2
0=0
