A line extending from the lower left to the upper right has a <em>positive</em> slope.
You would have to do distribution you would do 5(2x) which would give you 10 and 5(10) which gives you 50 so your equation would be -60=10x+50 then you would subtract 50 from both sides which would give you -110 your equation would be -110=10x divided 10 on both sides and your answer would be x=-11
