What is the equation of the following table of values?
y = x - 1
OR
How may total linear relations are present in the following?
What is the slope of a line whose change is y is 14 and change in x is -2?
-7
The y-intercept is
A. the value of the independent variable when the dependent variable is zero; sometimes called the initial value.
B. the value of the dependent variable when the independent variable is greater than zero; sometimes called the initial value.
C. the value of the dependent variable when the independent variable is zero; sometimes called the zero value.
D. the value of the dependent variable when the independent variable is zero; sometimes called the initial value.

Graph the following:
y = 2x + 4
What is the y-intercept for the line y = 24x + 23?
23
What is the slope of the line passes though points (2, 7) and (6, -1)?
-2
What is the slope and y-intercept of the following graph?
Y-intercept: 20
This internal body part is actually about 15 (or more) feet long
Is this relation linear? Explain why/why not.
YES
As x-values increase by 1, y-values increase by 3. x=3 is missing but the pattern remains consistent for x=4 and up.
Which graph represents the line y = -2x + 4?
C
A graph has a y-intercept of -5 and an x-intercept of -3. What is the slope?
`-5/3`
Given the linear equation y = -2x + 3, please tell me the missing values in the following ordered pairs:
(-3, y) and (x, -1)
y = 9
x = 2

A discrete function is a function with distinct and separate values. A continuous function, on the other hand, is a function that can take on any number within a certain interval. Discrete functions have scatter plots as graphs and continuous functions have lines or curves as graphs.
A sand castle shrinks in height by 5cm every hour. The castle started at 50cm and is completely gone after 10 hours.
a)How much did it shrink per hour?
b)What would be the slope of the graph?
c)What would be the y-intercept of the graph?
d)What would be the dependent variable for this situation?
a)5cm/hr
b) - 5
c)50
d)Height
A gym charges a set membership fee, then a set cost per visit, as seen in the diagram.
a)What is the cost per visit(aka the slope)?
b)What is the membership fee(aka the initial value)?
c)What is the equation for this relation?
a) $2/visit; Slope = 2
b) Membership fee is $40 ; initial value/y-int = 40
c) y=2x + 40
A museum offers two types of memberships:
1)$6 per visit OR 2) a flat fee of $10 and 3$ per visit
Which type would be better for more than 3 visits? Explain
2 because for 4 visits it is cheaper($22 vs $24) and after that it increases by $3/visit vs $6/visit
