Nami is correct since if a movie is PG-13 you have to be at least 13 yrs old or higher to enter. The sign is saying that you have to be 13 yrs old or younger to enter which is incorrect because a 5 yr old shouldn't be allowed to watch a PG-13 film for adults. The correct sign would be x≥13

A pair of equations is shown below:
Oksi-84 [34.3K]
If you graph y=7x-9 and y=3x-1 the two lines will intersect at one point.  That is how you graphically "solve" the system of equations.

Both of these lines are of the form y=mx+b where m is the slope and b is the y-intercept.

So for y=7x-9, the slope is 7 and the y-intercept is -9

For  y=3x-1, the slope is 3 and the y-intercept is -1

....

The solution for this system occurs when both coordinates are equal to each other so we can say:

7x-9=3x-1  subtract 3x from both sides

4x-9=-1  add 9 to both sides

4x=8  divide both sides by 4

x=2, making y=3x-1 become:

y=3(2)-1=6-1=5, so the solution to the system of equations is:
