Answer:
4
Step-by-step explanation:
There are 7 cards. The number of possible correct picks is 2 (if you pick an 'S') plus 1 (if you pick the 'U') = 3 ways to succeed. So the probability of success is 3/7 ... about 43% .
Rise

run
y2-y1
____
x2-x1
-1-4
___
2--2
-5
___
4
rise: -5
run: 4
Let y=0 to find the x-intercept(s).
0=−3x−4
Add 4 to both sides.
4=−3x
Divide both sides by -3
-4/3 =x (fraction)
Switch sides.
x=−4/3 (fraction)
Let x=0 to find the y-intercept(s).
y=−3×0−4
Simplify
y=−4
