$26.46 
I divided 15.12 by 8 to get the cost of just one gallon , which was $1.89. 14 x 1.89 = 26.46, which would ideally be the cost to fill a 14-gallon tank.

We are going to base the answer off of the y=mx+b form where m represents slope and b represents the y-intercept.
First, we know that b must be -1 because the line hits the y-axis when y is -1
So this leaves us with either the first or second choice
Then we choose two points to find the slope. I am using (0,-1) and (1,2). If you count the boxes, the y-value increases by 3 as the x-value increases by 1. So the slope is 3/1 or 3. 
So then we know the answer is y=3x-1
Hope this helps 
        
             
        
        
        
Answer:
24 = x
Step-by-step explanation:
You use Pythagorean theorem. Since the normal equation is  , you already have the
, you already have the  and another side which can be
 and another side which can be  or
 or  .
.
Because you have the hypotenuse and a side , your equation looks like this now:  
 
and when you solve for be you just subtract  to get 24.
 to get 24.
