8 Line in the xy-plane contains points from each of Quadrants II, III, and IV, but no points from Quadrant I. Which of the follo
iren2701 [21]

Answer:

The correct option is D.

Step-by-step explanation:

The slope of a line is the change in y with respect to x.

m=\frac{y_2-y_1}{x_2-x_1}

If the slope of a line is undefined it means it is a vertical line and a vertical line  can not passes through three quadrants. So, option A is incorrect.

If the slope of a line is 0 it means it is a horizontal line and a horizontal line  can not passes through three quadrants. So, option B is incorrect.

If the slope of a line is positive it means the value of y increases as x increases.

Since it is an increasing line, therefore after a certain period both x and y will positive. It means the line will passes through first quadrant. So, option C is incorrect.

If the slope of a line is negative it means the value of y decreases as x increases. It can passes through each of Quadrants II, III, and IV.

Therefore the correct option is D.

Answer:

Step-by-step explanation:

1a. 25/50 =x/100                

25*100= 2500/50= 50

A= 50%

1b. 35/40 = x/100

35*100= 3500/40= 87.5

A=87.5%

2a. 15/20= x/100

20*5= 100; 15*5= 75

A=75%

2b. 25/70= x/100

25*100= 2500/70= 35.71

A=35.71

3a. 15/80= x/100

15*100= 1500/80=18.75

A=18.75%

3b. 30/60= x/100

30/60= 1/2;1/2=0.5;0.5= 50%

A=50%

4a. 70/80 =x/100

70*100=7000/80 =87.5

A=87.5

4b.30/60 = 50% ( same as question #3b)
