Linear functions have a degree of 1.

Examples:

#2x+3y=9#
#y=4x+7#
#y=1/2x#

If the linear function is in slope intercept form, #y=mx+b#, then #m# indicates the slope and #b# indicates the y-intercept.

If the linear function is in standard form, #Ax+By=C#, then the slope is found by the quotient, #-A/B#.

If you want to find the x-intercepts substitute in a value of 0 for the #y# variables.

If you want to find the y-intercepts substitute in a value of 0 for the #x# variables.
