Answer:
x=5 and y=-2
Step-by-step explanation:
3x+5y=5
-(7x+5y=25)
-4x=-20
x=5
plug 5 into one of the equations. 3(5)+5y=5
y= -2
Answer:
![m=\frac{-3}{4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-3%7D%7B4%7D)
Step-by-step explanation:
Slope Formula: ![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Simply plug in 2 coordinates into the slope formula to find slope <em>m</em>:
![m=\frac{-4-(-1)}{5-1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-4-%28-1%29%7D%7B5-1%7D)
![m=\frac{-4+1}{4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-4%2B1%7D%7B4%7D)
![m=\frac{-3}{4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-3%7D%7B4%7D)
