Answer:
(B) y = -1/2x
Explanation:
A line has equation y = mx + b, in the slope-intercept form, where m = slope, and b = y-intercept.
The line passes through (0, 0), so the intercept is 0. b = 0. The equation of a line through (0, 0) is simply y = mx.
Now we use the points to find the slope, m.
m = ( 1 - 3)/(6 - 2) = -2/4 = -1/2
Now we replace m with the actual slope, -1/2.
y = mx
y = -1/2x
