Multiply 3 times x which gives you 3x then multiply 3 times -1 which gives you -3. Now you have an equation 3x-3=6. This is a two step equation so you have to add 3 (inverse operation) to 6 which gives you 9. Now you divide 9/3 which equals 3. The answer is 3
The standard form for an equation is y=mx+b. You find the slope by using the formula of rise over run. This means that for problem 6 you first look to see if its positive or negative slope. The slope is positive if the line is going uphill and if its going downhill its negative. The slope would be negative for number 6 because it is going downhill. Then for the actualy slope you would start with rise. So you look at the point (0,1) and go up 3 until you hit the line of the other point and run over 2. So your slope would be -3/2.

Well I’m guessing it went down by 20% to get to thirty pounds so
30 x 1.2 = $36 original price
Or if it’s lowered by 20% then
30 x 0.8 = $24
