First let’s find the equation:
a = (42-21)/(26-13)
a= 21/13
y-y1 = a(x-x1)
y-21=(21/13)(x-13)
y-21=(21/13)x - 21
y=(21/13)x-21+21
y=(21/13)x
Now we will find the other point:
X = 2 >> y =(21/13)*2 = 3.23 (not)
X = 3 >> y =(21/13)*3 = 4.84 (not)
X = 4 >> y =(21/13)*4 = 6.46 (not)
X = 5 >> y =(21/13)*5 = 8.07 (yes) find the answer

Answer:
y = -1/2 | x+3|
Step-by-step explanation:
y = f(x + C) C > 0 moves it left
C < 0 moves it right
y = Cf(x) C > 1 stretches it in the y-direction
0 < C < 1 compresses it
y = −f(x) Reflects it about x-axis
Our parent function is
f(x) = |x|
We want it 3 units left
y = f(x + 3)
y = |x+3|
Then reflected across the x axis
y = −f(x)
y = -|x+3|
Then shrink by 1/2 vertically
y = Cf(x)
y = -1/2 | x+3|
This question is incomplete, the complete question is;
You decide to record the hair colors of people leaving a lecture at your school. What is the probability that the next person who leaves the lecture will have blonde hair
?
Express your answer as a simplified fraction or a decimal rounded to four decimal places.
Blonde Red Brown Black Gray
31 25 18 40 42
Answer: the probability that the next person who leaves the lecture will have blonde hair is 0.1987
Step-by-step explanation:
Given that;
HAIR COLOR FREQUENCY
Blonde 31
Red 25
Brown 18
Black 40
Gray 42
Total 156
So
there were 156 people all together
and out of the 156, 31 of them were blonde.
now the probability that the next person who leaves the lecture will have blonde hair will be;
⇒ 31 / 156 = 0.1987
Therefore, the probability that the next person who leaves the lecture will have blonde hair is 0.1987
