Given two points
and
, the equation of the line passing through them is

This formula, however, only works if the points don't share any of the two coordinates. Otherwise, one of the two conditions is true:

And at least one of the denominators in the formula above will vanish.
So, if two points share the same x coordinate, they lie on the vertical line x=k, where k is the shared x coordinate.
Similarly, if two points share the same y coordinate, they lie on the horizontal line y=k, where k is the shared y coordinate.
In your case, the x coordinate is the same, so the points lie on the vertical line x=10.
Time is -b/2a, which is 3.
f(3) = 24 = maximum congestion
Answer:
x = -4
Step-by-step explanation:
-79 = 7x+12x-3
-79 = 19x-3
-19x = 76
x = -4
First we need to add the time she takes warming and the time she takes going to the the gym:

Next, we area going to subtract those 45 minutes from the time the game begins:
We can conclude that she should leaver her house at 6:00 pm if she wants to get in time for her 6:45 pm game.
