Answer:
y=0.5x-1
Step-by-step explanation:
First you need to find the gradient of the line. Since x goes up by 0.5 every time y goes up by 1, the gradient is 0.5. Then you need to find the y intercept which is what x equals when y is equal to 0. When y equals zero x equals negative 1. If ylu use the equation y=mx+c where m=gradient and c=y intercept you get y=0.5x-1

Answer:

Step-by-step explanation:
Hello!
We can use the factored form of a Quadratic to find an equation with 8 and -8 as our solution.
<h3>
Factored Form: 
</h3>
The value in each parenthesis should be 0. So 8 and -8 can be flipped and used for h and k.
This will give roots 8 and -8 for x.
A possible equation is
.
53.70 - 9.60 = 44.10. 44.10 / 2 = 22.05. Each friend paid (not including the tip) $22.05.
