Patterns
These patterns add/subtract a constant value.
ARITHMETIC patterns
In which quadrant would the point (-4, 7) be placed?
2 1
3 4
Coordinate, ordered pair
(x, y) Quadrant 2
Write the FORMAT for slope-intercept equations:
y = mx + b
or
y = b + mx
The angle of the steepness of a line
"rise over run".
Slope
These patterns multiply / divide a constant value.
GEOMETRIC sequences
Describe what the y-intercept would tell us about a situtation.
Y-intercept is the starting value before a pattern of change.
Write the FORMAT for STANDARD FORM equations:
ax + by = C
TRUE or FALSE?
Any coordinate point that sits on the line of that equation is a solution.
TRUE. A Solution
Draw an example of the 4 common types of slope:
Positive:
Zero:
undefined:
Negative:
The point(s) where our line crosses the X or Y axis.
Intercept:
x-intercept and y-intercept
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.
The pattern of a linear function is also called ___.
Slope
What are 3 other terms for PATTERN?
Rise over Run
Rate of Change
SLOPE
Movement
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
Find the x and y intercept
4x + 3y = 24
(6, 0) (0, 8)
What is the slope of a line with points
(1, 5) and (-9, 10)?
Rise 5 -1
Run -10 2
If a slope says 4
describe the movement on the graph.
Rise 4 units, move forward 1 unit
3x + 21 = 11x + 5
Solve for x
x = 2
Find the x and y intercept:
-6x + 12y = -36
x-intercept: (6 , 0)
y-intercept: (0, -3)
