Answer:
![y = 1x - 4](https://tex.z-dn.net/?f=y%20%3D%201x%20-%204)
Step-by-step explanation:
You have to solve for the x intercept on the equation
![2x-5y=8\\2x-5(0)=8\\2x=8\\x=4\\(4,0)](https://tex.z-dn.net/?f=2x-5y%3D8%5C%5C2x-5%280%29%3D8%5C%5C2x%3D8%5C%5Cx%3D4%5C%5C%284%2C0%29)
That is the x intercept for that equation.
Then solve for the y intercept on the equation
![4x-3y=12\\4(0)-3y=12\\-3y=12\\y=-4\\(0,-4)](https://tex.z-dn.net/?f=4x-3y%3D12%5C%5C4%280%29-3y%3D12%5C%5C-3y%3D12%5C%5Cy%3D-4%5C%5C%280%2C-4%29)
That is the x intercept for that equation.
Use that to find slope for point slope form
![\frac{y_{2}-y_{1}}{x_{2}-_{1}} \\\\\frac{-4-0}{0-4} \\\\\frac{-4}{-4} \\\\1](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-_%7B1%7D%7D%20%5C%5C%5C%5C%5Cfrac%7B-4-0%7D%7B0-4%7D%20%5C%5C%5C%5C%5Cfrac%7B-4%7D%7B-4%7D%20%5C%5C%5C%5C1)
1 is the slope
and slope makes B the y intercept so the equation is
![y = 1x - 4](https://tex.z-dn.net/?f=y%20%3D%201x%20-%204)

Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -2x + 9
y = 3x + 9
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 3x + 9 = -2x + 9
- [Addition Property of Equality] Add 2x on both sides: 5x + 9 = 9
- [Subtraction Property of Equality] Subtract 9 on both sides: 5x = 0
- [Division Property of Equality] Divide 5 on both sides: x = 0
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = -2x + 9
- Substitute in <em>x</em>: y = -2(0) + 9
- Multiply: y = 0 + 9
- Add: y = 9
5x=-35 divide both sides by 5 to get
x=-7
