Graphing Lines in all forms

Question 1

What are the three forms of linear equations?

Answer 1

standard
point slope
slope intercept

Question 2

What doe standard form of a line look like?

Answer 2

Ax + By = C (notice the capital letters)

Question 3

Why are the A, B and C capital in standard form linear equations?

Answer 3

Because they represent INTEGERS

Question 4

What are INTEGERS?

Answer 4

Whole numbers, positive and negative and zero

… -3, -2, -1, 0, 1, 2, 3…..

Question 5

How do you graph in standard form? Ax + By = C

Answer 5

Find the intercepts by plugging in zeros
(0,   )
(  , 0)
Plot the intercepts, label and connect.
SLOPE IS m =  -A / B   or    (opposite A/ B)

Question 6

What is the y intercept in Standard form? Ax + By = C

Answer 6

The y intercept is C/B
