#y = color(red)(1/3)x + color(blue)(6)#

The slope-intercept form of a linear equation is:

#y = color(red)(m)x + color(blue)(b)#

Where #color(red)(m)# is the slope and #color(blue)(b)# is the y-intercept value.

In this problem the slope is given as #color(red)(m = 1/3)#

Also, because the second point has the #x# value of #0# the y value is therefore the #y# intercept or #color(blue)(b = 6)#

Substituting these into the formula gives:

#y = color(red)(1/3)x + color(blue)(6)#
