Question 485015: How do I find the slope of y= -2x +5. How do I find the value of x at which the 2 lines y=2x+1 and y= -1/4x + 3 intersect. I am completely confused, please if someone can show me step by step to get a solution to both of these. Thank you.

slope =m
y=mx+b
slope m=-2
-------------
y=2x+1
y=-1/4x+3
------------
2x+1=-1/4x+3
2x+1/4x=2
2 1/4x=2
x=2/(2 1/4)
x=2*4/9
x=8/9
------------
y=2(8/9)+1
y=16/9+1
y=25/9
y=2 7/9
------------
(8/9,0)
(0,2 7/9)
--------------
