Slope-intercept form:
y = mx + b "m" is the slope, "b" is the y-intercept (the y value when x = 0)
Since you know m = 7/2, plug it into the equation
y = 7/2x + b
To find "b", plug in (-12,-9) into the equation
y = 7/2x + b
-9 = 7/2(-12) + b
-9 = -84/2 + b
-9 = -42 + b Add 42 on both sides
33 = b
(if you're not suppose to use slope-intercept form)
Point-slope form:
y - y₁ = m(x - x₁)
m = 7/2
(x₁ , y₁) = (-12,-9)
Plug this into the equation
y - y₁ = m(x - x₁)
y - (-9) = 7/2(x - (-12))
A graph's correlation between two variables reveals the relationship between them. The correlation is given a name based on the characteristics of the variables represented on the graphs.
What does the term correlation mean?
The data points of a person with two different factors are related in a scatterplot. The term "correlation" refers to this connection.
A correlation is the relationship between any two variables represented on any graph.
The correlation is divided into three main categories based on the sort of relationship between the variables. Those are
i) Positively correlation
ii) Negative correlation
iii) No correlation

Answer:
A The mean for waiter B is higher than the mean for waiter A.
Answer:
a. x = 13m, b. x = 12cm
Step-by-step explanation:
a. x² = 12² + 5² (Pyth. theorem)
x = 13 m
b. 15² = 9² + x² (Pyth. theorem)
x = 12 cm
