The basis for this equation is #y=mx+b#, where #m# is the slope and #b# is the #y#-intercept.

So, #y=-2x+10# tells us that the slope is #-2/1# or down #2# units, over #1# unit, and that the #y#-intercept is #10#.

So, we start at #(0,10)#. If we go down #2# and over #1#, we subtract #2# from #10# and add #1# to #0#

Our new coordinate pair is #(1, 8)#. If we keep going we can make a line, but you should have enough information to make graph

graph{y=-2x+10}
