the variable m
100
What form do we use to graph a linear equation?
the slope-intercept form y = mx + b
100
What is slope intercept form?
y = mx + b

Evaluate:

-2 - 5

-7

Which graph would be steeper? How can you tell?


A: y = 3x +7 

B: y = 6x - 2

B would be steeper because it has a greater slope.

200
Identify the slope of the following equation. y = 2x + 3
slope is 2
200
When graphing linear equations, where do we begin?
We begin at the y-intercept.
200
In the following linear equation, what is the y-intercept? y = -3/4x
0
200

Solve:

3x - 2 = -14

x = -4

Which graph is more slanted? How can you tell.


A: y = -2/3x + 4

B: y = -1/2x - 7

A would be more slanted because it has a lower negative slope.

Name three ways to describe slope.
Possible answers: rate of change rise over run y - y x - x slope = m in y = mx + b

Graph the following equation. Include at least 3 points. y = 1/3x + 4

Graph should start with the point at (0, 4) Movement should be 1 up and 3 to the right continuing to another point. Movement could also be 1 down and 3 to the left.

Write an equation that would produce a line parallel to:

y = 2x - 8

Any equation with the same slope and a different y-intercept would be acceptable.

Describe how to find slope and y-intercept from a graph. 

The y-intercept is the point where a function crosses the y-axis. The slope is found by picking two points and counting the distance between them. First, you could up/down then right/left

Describe in words how to graph the linear equation:

y = -4x + 3

Starting at 3 on the y-axis, count down 4 and right 1 to create points until the graph is completing filled in.

Make a table of values with at least 4 ordered pairs for the following equation:

y = 0.5x - 5 .

*Miss Fricke will check answers*

Solve:

2(x + 5) + 3 = 5x - 16

x=1

The amount y(in dollars) of money you have left after playing x games at a carnival is y = -0.75x + 10. How much money do you have after playing eight games? 

y = -0.75(8) + 10 y = -6 + 10 y = 4 $4 dollars left after playing 8 games.
