You can write the linear equation in the point-slope form .

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

where #m# is the slope, #4#, and the point #(1,3)# is #(x_1,y_1)# .

Point-slope form: #y-3=4(x-1)#

This equation can also be written in slope-intercept form by solving for #y# . The general form is #y=mx+b#, where #m# is the slope and #b# is the y-intercept.

#y-3=4(x-1)#

Distribute the #4#.

#y-3=4x-4#

Add #3# to both sides.

#y=4x-4+3# =

Slope-intercept form: #y=4x-1#
