Identifying Linear Functions
What is a function whose graph forms a straight line called?
linear function
What is the standard form of a linear equation?
Ax+By=C
Tell whether the function is linear and turn it into standard form of linear equation: y=x+3
Yes can be written as -x+y=3
How do you know when you have perpendicular slopes?
When the product of the slopes equal -1 OR the slopes are negative reciprocals.
Tell whether the function is linear and graph the function. 3x-2y=12
Yes it is linear.
