PLEASE ANSWER THIS ASAP !!!!! ( turn sideways )

Answer:
y = 1/2x
Step-by-step explanation:
y-intercept is (0, 0)
pick any point, let's say (-4, -1). Let's apply rise over run, rise up 2 points then run 4 points over to arrive at (4, 1). So, your slope is 2/4 which simplify to 1/2.
Equation of line:
y = mx + b
m is your slope
b is y-intercept
y = 1/2x + 0 same as y = 1/2x
