Isosceles because it has two sides the same length, not matching the third.

Slope-intercept form is y = mx + b. all you have to do for this question is plug your given information in:
m = -3
b = 7
y = mx + b
y = -3x + 7
If that is a square to the parenthesis then it would be D. the formula is (x-h)^2+(y-k)^2=r^2
There are 4 Queens, 4 Kings, and 4 Aces in a standard deck of cards.
Add these together, and there are 12 cards that you have a chance of choosing from.
The ratio of cards we want to get (queen, king ace) to number of cards is 12/52. This is the probability. We can simplify it further by dividing both sides by 4. We now have the fraction 3/13.
Therefore, the probability of drawing a queen, king, or ace is 3 in 13, or 23%.
hope this helped!
