3x + 2y = 6
(Put in Standard Form) y = -3/2x + 3
5x - 4y = 7
(Put in Standard Form) y = 5/4x - 7/4
4x + y = -2
(Put in Standard Form) y = -4x - 2
4/3
Slope=? (0, 0) and (3, 4)
4/9
Slope=? (1, 1) and (10, 5)
2
Slope=? (-2, 3) and (-4, -1)
y = -2x - 7
(Transform into slope intercept form) 2x + y = -7
y = -3/4x + 3
(Transform into slope intercept form) 3x + 4y = 12
y = -2x - 9
(Transform into slope intercept form) -y - 2x = 18
y int: -2
(Find y intercept, and slope) y = 1/3 x - 2
y int: 10
(Find y intercept, and slope) y = 2x +10
y int: 0
(Find y intercept, and slope) y = 0.37x
function
If you repeat an INPUT, and you always get the same OUTPUT, your data is a ______________________ .
Domain
The ______________________ is all the possible INPUT, X, values.
Range
The difference between the greatest number and the least number in a set of data.
Relation
A Smart Art graphic type that compares connections between concepts.
VERTICAL LINE TEST
A line is a function is it passes the
f(x)
f of x
Function table
a table organizing the input, rule, and output of a function
Linear Equation
A polynomial equation of the first degree whose graph is a line.
x-intercept
the point where the line crosses the x-axis
y-intercept
the point where the line crosses the y-axis
slope
(y₂-y₁)/(x₂-x₁)
Rate of chage
change in Y/ change in X
Constant rate of change
the rate of change between any two data points is the same
Positive slope
Moves up
Negative slope
