Let's graph -10y<60.
1) Solve for y. Doing this requires a little trick: you must reverse the direction of the inequality sign:
Divide both sides of the equation by -10, and at the same time
substitutte > for <:
-10y < 60
------ ------ => y > 60 / (-10), or y > - 6 (answer)
-10 -10
To graph this, use a dashed (not a solid) line. Locate y = -6 on the y-axis and draw a dashed, horizontal line through it. Done!
