#y = -2x+5#

Explanation:

The slope-intercept form of a line gives us the equation of a line with slope #m# and #y#-intercept #b# as

#y = mx+b#

(Notice that this makes sense, as an increase of #1# by #x# results in an increase of #m# by #y#, making the slope=#"rise"/"run"# formula result in #m/1#, and setting #x=0# gives #y=b# as the #y#-intercept)

Plugging in #m=-2# and #b=5#, we get the equation as

#y = -2x+5#
