A linear function models a straight line that has a constant slope or rate of change.

There are various forms of linear equations.

Standard Form

#Ax+By=C#

where #A, B and C# are real numbers.

Slope Intercept Form

#y=mx+b#

where #m# is the slope and #b# is the #y#-intercept

Point Slope Form

#(y-y_1)=m(x-x_1)#

where #(x_1,y_1)# is any point on the line and #m# is the slope.
