1. The equation y=mx+b is linear this is because that y always x is always increased by the same number. and although you add b it does nothing exept increase the begining number by what ever it is because you add it after the multiplacation.

2.a. A graph would prove a equation lineir and tell you how much to increase each time. However a table tells you the anser but only to some extent because the graph could not go on for ever.

b. A equation is quite simple to solve, it is just like a math problem but with a variable. Like if m=7 x=4 and b=3 than it would be a problem like y=7*4+3 than y would equal 32.
