Answer:
Step-by-step explanation:
![slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{3-(-2)}{9-2}\\\\=\frac{3+2}{7}\\\\=\frac{5}{7}](https://tex.z-dn.net/?f=slope%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C%3D%5Cfrac%7B3-%28-2%29%7D%7B9-2%7D%5C%5C%5C%5C%3D%5Cfrac%7B3%2B2%7D%7B7%7D%5C%5C%5C%5C%3D%5Cfrac%7B5%7D%7B7%7D)
the equation describes a horizontal line with a y-intercept of -4. as the line is horizontal, the slope is 0.

Answer:
Solution: (4,-5)
Step-by-step explanation:
Given: system of equation, y=2x-13 and y=x²-6x+3
using substitution method,
substitute y=2x-13 into y=x²-6x+3
![2x-13=x^2-6x+3](https://tex.z-dn.net/?f=2x-13%3Dx%5E2-6x%2B3)
![x^2-6x-2x+3+13=0](https://tex.z-dn.net/?f=x%5E2-6x-2x%2B3%2B13%3D0)
![x^2-8x+16=0](https://tex.z-dn.net/?f=x%5E2-8x%2B16%3D0)
![(x-4)(x-4)=0](https://tex.z-dn.net/?f=%28x-4%29%28x-4%29%3D0)
![x=4,4](https://tex.z-dn.net/?f=x%3D4%2C4)
Put x=4 into y=2x-13
y = 2(4) - 13
y = 8-13
y = -5
Solution: (4,-5)
