![y=-3\left(x+6\right)](https://tex.z-dn.net/?f=y%3D-3%5Cleft%28x%2B6%5Cright%29)

Step-by-step explanation:</h2>
From the given graph, we can know two points:
![P_{1}(x_{1},y_{1})=(2,0) \ and \ P_{2}(x_{2},y_{2})=(1,3)](https://tex.z-dn.net/?f=P_%7B1%7D%28x_%7B1%7D%2Cy_%7B1%7D%29%3D%282%2C0%29%20%5C%20and%20%5C%20P_%7B2%7D%28x_%7B2%7D%2Cy_%7B2%7D%29%3D%281%2C3%29)
Using the slope intercept form of the equation of a line, we get:
![y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1}) \\ \\ y-0=\frac{3-0}{1-2}(x-2) \\ \\ y=-3(x-2) \\ \\ y=-3x+6](https://tex.z-dn.net/?f=y-y_%7B1%7D%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%28x-x_%7B1%7D%29%20%5C%5C%20%5C%5C%20y-0%3D%5Cfrac%7B3-0%7D%7B1-2%7D%28x-2%29%20%5C%5C%20%5C%5C%20y%3D-3%28x-2%29%20%5C%5C%20%5C%5C%20y%3D-3x%2B6)
Where the slope is
and the y-intercept is ![b=6](https://tex.z-dn.net/?f=b%3D6)
From mathematics, we know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept. So, from the options, the second equation is:
![y=-3(x+6)](https://tex.z-dn.net/?f=y%3D-3%28x%2B6%29)
And the slope intercept form of this equation is:
![y=-3x-18](https://tex.z-dn.net/?f=y%3D-3x-18)
So the slope is
and the y-intercept is
, the systems formed by these two equations has no solution.

Answer:
Right triangle
Step-by-step explanation:
7^2 + 6^2 = c^2
49 + 36 = c^2
85 = c^2
c = 9.22
2.75 is 110%
2.75/1.1=2.50
Therefore, the main bill was two and a half dollars
