Because she has more COLORED shirts then WHITE shirts it is likely she will pick a COLORED shirt.
11 +9 = 20 total shirts
probability for a colored one = 11/20
Since we have two ordered pairs, we can find the slope by plugging them into (y2-y1)/(x2-x1) which translates to (3-(-6))/(-4-(-1))=9/-3=-3
Since the slope is -3, we have the equation y=-3x+b, but we don't know b. So we plug in values for x and y and solve for b.
-6=-3(-1)+b
-6=3+b
-9=b
So the y-intercept is -9 and the full equation is y=-3x-9 which means A is the only correct answer.
Hope this helped!
Please comment on this answer and give me a full question and I will be just fine answering it for you.
The answer is zero, i think
