what I learned about grade 9 linear relations

We learned to find patterns. I learned how to do more simple to find the law of the problem. It can follow the formula. For example, 14,  , , , 32, , , you can use (32-14)/3. Because there are three intervals between 14 and 32. And we learned analytic expressions, learned how to draw a form to find the answer. For example, 2+3=5. So the 2,5,8 interval is 3, and then add 3. Three decreases one is two. So the answer is 3X-1=y.

Inequalities blog post

We learned how to solve inequalities, When you see a problem you first have to separate the unknowns from the Numbers, And then you figure out the Numbers. When you check your answers, You have to put the answer into the unknown. If it’s equal to, greater than or less than or equal to that number, That’s the right number. like: 4x+1>4. You put the 1 on the right hand side, and it becomes four minus one, So 4X is greater than 3. X is the unknown number. Divide three by four, so the answer is 3/4.
