why doesnt any math teacher in the world do problems that are like in the homework not the most simple forms of an equation...annoying

[@johnlawrence9495]

It is to challenge your mind. It supposed to test if you can think outside the box. If the teachers just show everything to you. You are not gonna develope critical thinking.

[@miranda0298]

@@johnlawrence9495 but if i don't learn how to do a certain part of an equation i've never seen before, i can't solve it. shouldn't teachers be showing you how to do every type of equation so that you can memorize how to do it? that still takes work and practice on the student's part, but at least you're learning it. you can't expect kids to do well on something they weren't taught.

[@Dm-dw3tr]

some schools require a teacher to teach a certain way. Most time it is not up to the teacher to teach the way that is best for the student or classroom. I have friends in our local district that complain about this a lot. They must follow the rules or else find a new job.

assume some value for x, and find the respective value for y. suppose x=1. put it in ur eq and find y. similarly put x=2 and find y.......now draw the line by joining the co-ordinates maybe this would help

The y intercept is 0. So y = 3/4x + 0 .. you know you're going to have a point on the graph that intersects (0,0).
