Answer:

Make #y# the subject of the formula.

Explanation:

Write an equation which has an #x#-term, a #y#-term and a number term so that #y# is the subject of the formula.

The process would be to isolate the #y# term on the left and then to divide each term by the numerical coefficient of #y#

As an example:

#3x color(blue)(+5y) = 20#

#color(blue)(5y) = -3x+20#

#y = -3/5x -20/5#

#y = -3/5x-4" "larr# slope-intercept form#
