Answer:

#y=(4x)/5+2#

Explanation:

Lines are written in the form #y=mx+b#, where #x# and #y# are points on the line, #m# is the slope, and #b# is the #y#-intercept. Since we're finding a general equation of the line, we don't have to touch #x# and #y# (which are general points).

We are told that the slope, #m#, is #4/5# and the #y#-intercept, #b#, is #2#. Since lines are expressed as #y=mx+b#, we just make substitutions to get #y=(4x)/5+2#.
