3 4
Coordinate, ordered pair
(x, y) Quadrant 2
100
Write the FORMAT for slope-intercept equations:

or
y = b + mx
100
The angle of the steepness of a line
"rise over run".
Slope
100
Write the inequality for the graph.
y <= 3 + 3/2x
200
These patterns multiply / divide a constant value.
GEOMETRIC sequences
200
Describe what the y-intercept would tell us about a situtation.
Y-intercept is the starting value before a pattern of change.
200
Write the FORMAT for STANDARD FORM equations:
ax + by = C
200
TRUE or FALSE?
Any coordinate point that sits on the line of that equation is a solution.
TRUE. A Solution
200
Write the inequality for the graph.
y < 1 - 3x
300
Draw an example of the 4 common types of slope:
Positive:
Negative:
Zero:
undefined:
300
The point(s) where our line crosses the X or Y axis.
Intercept:
x-intercept and y-intercept
300
What does the term substitute mean?
(when we are finding x and y intercepts we use 0)
Replace an unknown variable with a known value.
300
The pattern of a linear function is also called ___.
Slope

yes
400
What are 3 other terms for PATTERN?

Rate of Change
SLOPE
Movement
400
Where do we START when we are about to graph a point?
Origin (0,0)

Solve for x: 5(2x - 11) = -15
5(2x - 11) = -15
10x - 55 = -15
10x = 40
x = 4
400
Find the x and y intercept
4x + 3y = 24
(6, 0) (0, 8)
400
Find the 2 solutions *leave fractions as fractions*
|3x - 1| = 14
3x - 1 = 14 3x - 1 = -14
x = 5 x = -13/3
500
What is the slope of a line with points
(1, 5) and (-9, 10)?
Rise 5 -1
Run -10 2
500
If a slope says 4
describe the movement on the graph.
Rise 4 units, move forward 1 unit
500
3x + 21 = 11x + 5
Solve for x
x = 2
500
Find the x and y intercept:
-6x + 12y = -36
x-intercept: (6 , 0)
y-intercept: (0, -3)
