Slope of line connecting Q and O =?
Slope = \(\frac{y2 - y1}{x2 - x1}\)
Coordinates of Q = (-4,-2) = (x1,y1)
Coordinates of O = (0,0) = (x2,y2)
Slope = \(\frac{0 - (-2)}{0 - (-4)}\) = \(\frac{2}{4}\) = 0.5
So, correct answer is option D.
Slope = \(\frac{y2 - y1}{x2 - x1}\)
Coordinates of Q = (-4,-2) = (x1,y1)
Coordinates of O = (0,0) = (x2,y2)
Slope = \(\frac{0 - (-2)}{0 - (-4)}\) = \(\frac{2}{4}\) = 0.5
So, correct answer is option D.

Slope of OQ = (y2- y1)/(x2 -x1) = {0-(-2)} / {0-(-4)} = 0.5
So, I think D.
