Answer:
The given table represents a function f(x) = y = 2x+3
The upper graph
Step-by-step explanation:
We will write the equation of the right line in the explicit (slope) form
y = ax+b
We will take two points from the given table
A(-1,1) and B(0,3) and insert their coordinates in the equation y=ax+b and get
A(-1,1) => 1 = (-1)*a+b => -a+b=1
B(0,3) => 3=0*a+b => 3= 0+b => b=3
Now we will insert b=3 in the equation -a+b=1 and get
-a+3=1 => a=3-1 => a=2
Now we will insert a=2 and b=3 in the equation y=ax+b and get
equation of the function
y = 2x+3 = f(x) The upper graph.
Good luck!!!
Answer:
The slope of the line is 2.
Step-by-step explanation:
Slope of a line:
Suppose that we have two points. The slope of the line is given by the change in y divided by the change in x.
In this question:
Points (0,0) and (1,2)
Change in y: 2 - 0 = 2
Change in x: 1 - 0 = 1
Slope: 
The slope of the line is 2.

Answer:
If 11 people use all three facilities, this means:
22 − 11 or 11 are using the gym and the pool but no the track,
29 − 11 or 18 are using the pool and the track but no the gym,
25 − 11 or 14 are using the gym and the track but no the pool.
How many people use the gym only?
130 − (14 + 11 + 11) = 94
How many people use the pool only?
62 − (18 + 11 + 11) = 22
How many people use the track only?
58 − (14 + 11 + 18) = 15
How many people go in for sports?
94 + 22 + 15 + 11 + 14 + 18 + 11 = 185
How many people use exactly one of the facilities?
94 + 22 + 15 = 131
What is the probability that the person uses exactly one of the facilities?
= 131/185 ≈ 0.7081
Step-by-step explanation:
its a bit confusing
Hope It Helps !!!!
