The slope-intercept form of a line is:

$y = mx + q$

Where m is the slope and y is the y-intercept:

$y = 3x + q$

To find q (y-intercept), substitute the coordinates of the point (9, -4) in the equation of the line and solve it as an equation:

-4=3(9)+q
-4=27+q
q=-27-4=-31

The equation of the line is: y=3x-31

Answer:

Answer is D (got it right on plato)

Step-by-step explanation:

There are 4 of each king and queen in each standard deck of 52 cards.

4+4=8

8/52=0.1538 or 15.38%

Twenty cards are chosen from a pack of cards at random

In A there are 0 kings and 1 queen

0+1= 1; 1/20=.05 or 5%

In B there are 2 kings and 4 queens

2+4=6; 6/20=0.3

In C there are 0 kings and queens

0/20=0

In D there are 2 kings and 1 queen

2+1= 3; 3/20=0.15 or 15%

D is your answer because it is the closest to the probability (0.1538 or 15.38%)
