linear functions A
What is a linear Function?
A function that represents a straight line on a coordinate plane.
what is a y-intercept
where the line crosses the y-axis
why is linear function called linear?
variable can be represented and graphed in straight line.
What do intercepts represent?
The points on a graph that crosses an axis.
How are linear functions used to show relationships between quantities?
Produce or graph a straight line.
How are linear functions used in real life?
Calculating mileage rates, predicting profit.
What does X slope mean?
The slope of a line is the steepness of line.
how do you determine if a function is a linear, constant, or niether?
if the points have the same slope.
what does the X- intercept represent in a word problem?
the point where the graph of a line cross the x-axis
What are the 3 major forms of linear equations?
Point-slope form, standard form, and slope intercept
What is special about Linear function equations?
Linear functions graph a straight line.
What does the Y intercept represent?
The Y value when the X value is 0.
how do you know if it is a linear function?
the change in Y always going to be the same value.
what does the x intercepts represent?
The point at which at the graph of an equation crosses over
How do you know if a problem is a linear function?
Check to see if there's a constant rate of change.
Why is a linear function called a linear?
Its represented by a straight line.
What is the Y intercept in math?
When the line touches the Y axis.
what is Standard form?
Ax+By=c
Who created linear functions?
Sir William Rowan Hamilton
What is special about linear functions equations?
Linear Functions are those who graph a straight line.
Does a linear function have a constant rate of change?
A Linear function does have a constant rate of change.
What do you need to graph a line?
slope and y-intercept
or x and y - intercepts
What is a linear equation in standard form.
3y = 2/3x +2
-2x + 9y = 6
How do you write an equation for a linear function.
y= mx + b
How are linear functions used in real life?
Figuring out income, overtime, calculation mileage etc.
