Question 178029: Linear System
Use the graphing to find the point of intersection of each pair of lines.
b) y=1/2x-4
y=2x-1
f) x+y-4=0
5x-y-8=0
Can you pleaseeeeee do both of them because i have to do a, c, d, e, and g for that i need to understand b and f okay thank you sooo much

Ans: (-2,-5)
=========================================================

f)
x+y-4=0
5x-y-8=0

Rearrange:
y = -x - 4
y = 5x -8
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C-x-4%2C5x-8%29
Ans: (2/3 , -14/3)
