Question

What is the equation of the line graphed below?y(5,2)O A. y=-2/xOB. y=-J|NC. y = 2/2 X2xO D. y =-55-5

Answer 1

To answer this question we will use the following two points formula for the equation of a line:

`y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1).`

From the given graph we get that the line passes through (0,0) and (5,2), then its equation is:

`y-0=(2-0)/(5-0)(x-0).`

Simplifying the above result we get:

`y=(2)/(5)x.`

Answer: Option D.
