Question

What’s in a equation or Leniar function y axis 1 and negative 7 and x axis negative 3 and 1

Answer 1

A linear function is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. For example, a common equation,  

y

=

m

x

+

b

, (namely the slope-intercept form, which we will learn more about later) is a linear function because it meets both criteria with  

x

and  

y

as variables and  

m

and  

b

as constants.  It is linear: the exponent of the  

x

term is a one (first power), and it follows the definition of a function: for each input (

x

) there is exactly one output (

y

).  Also, its graph is a straight line.
