Slope-Intercept Form
Write the slope-intercept form of a line with slope 3 and y-intercept 2.
y = 3x + 2
Simplify: 1/2 + 1/3.
5/6
Simplify: 8 + 3 × 2.

Solve x+7=12
x=5
This is a type of relation where each input is mapped to exactly one output
What is a function
Given the equation y = -2x + 5, what is the slope and what is the y-intercept?
slope = -2, y-intercept = 5
Simplify: 3/4 - 5/8.
1/8
Simplify: (6 + 2) × 5 - 4.

Solve 3x=18
x=6
Is the following a function: {(1,2), (2,3), (1,4)} why or why not?
No because 1 goes to 2 and 4
Graph the line y = 1/2 x - 1.
y-intercept at (0,-1) with slope of up one, right 2
Multiply and simplify: (2/3) * (9/4).
3/2
Simplify: 2(3x + 4) - 5 when x = 2.
15
Solve 2x+5=17
x=6
Given f(x) = 2x + 1, what is f(3)?
f(3)=7
Find the slope of the line that passes through the points (4, -2) and (6, -6)
What is -4/2 OR -2
Divide and simplify: (7/8) ÷ (3/16).
14/3
Simplify: 4(2 + x) - 3(x - 1) when x = 5.
16
This is name of the value that makes a situation true
What is a solution?
Identify the domain and range (from the listed points): {(−1,2), (0,0), (2,5), (4,5)}.
Domain = {−1, 0, 2, 4}; Range = {2, 0, 5}
The is the word we use to describe the point at which a line crosses the y-axis
What is the y-intercept
Simplify and write as a single fraction: 5/6 + 2/3 - 1/4.
5/4
This is the name of the number that multiplies a variable, for example: 2 is the ___ in the term 2x
What is the coefficient
This is what we call it when we manipulate an equation to get a variable alone on one side
What is isolate
The set of all possible input values (or "x" values) for a function
What is the domain
