Iiiiiiiiiiiiiiiiiiiiii ammmmmmm not sure
Answer:
y =
x
Step-by-step explanation:
the equation of a line passing through the origin is
y = mx ( m is the slope )
calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 3) ← 2 points on the line
m =
=
= 
y =
x ← equation of line

Answer: B
Step-by-step explanation: I took the quiz and got it right

Is this more then one question?
