Question

HELP ASAP PLZ GUYS!!!!!! THANKS IN ADVANCED WILL MARK BRAILEST... 12 POINTS

Answer 1

The answer is Y=40x

Answer 2

Answer:

Truck B is going 40 miles /hour

Answer A

Step-by-step explanation:

First of all the equation is going to be of the form y = ax just as "a" is. You need a couple of points. The question you need to answer is this "Is the slope more or less than 55?" You don't really know because the point are not labeled in any way that would give you an answer.

Rules and Line A

So you have to make up a mini problem that will tell you what is going on. It does not matter what units you choose at all, just as long as you are consistent with both graphs. So let's assume each square is worth 5 mph going up the y axis. Let us further assume that each square on the x axis is one hour. So for line A if you go up 6 squares up the y axis and 5 units across,  the slope will be 6*5 miles / 5 hours = 5 miles / hour

Line B

Now we work on the answer for the question by finding out what line B is doing. We choose the point where y axis has a value of 2 and the x axis is 3

The slope is then  5*2miles /3 hours = 3.3 which means that the vehicle for B is moving at a rate of 3.3 miles in 1 hour.

This does not represent anything in the real world. It is just to see if truck is moving faster or slower than truck A

Answer

Since the slope of line B is less than line A using my numbers, then Truck B must be travelling slower than line truck A.

Answer A is the only answer less than 55, so 40 mph must be the answer.
