Question 359826
What is an equation for a line that passes through the origin
 and is parallel to the line 2x-y=5?
:
Find the slope (parallel lines have the same slope) 
2x - y = 5
-y = -2x + 5
y = 2x - 5 (multiplied by -1)
m = 2
:
Find the equation when m = 2, x=0,y=0 (origin)
y - 0 = 2(x - 0)
y = 2x; is the equation
