Presentation transcript:

Warm up Multiply or divide the given fraction make sure to reduce 1) 4 x ) 3 ÷ ) Paraphrase the rules for Addition, Subtraction, multiplication, and division of fractions.

The two most common used linear functions 1) Standard Form- Ax + By = C  A, B, and C must be Integers. Also, the variables x and y Examples - 4x + 3y = 5x – y = 0 -3x + y = -4y = 3

The other one 2) Slope-intercept form: y = mx + b  m = slope b = y – intercept x and y are the variables that will remain constant. m and b can be any type of number, fraction, decimal, integer. One rule that must be followed is that y must be isolated Examples y = 3x + 2y = (1/2)x – 4 y = -7x

Lets try some together Identify the following equations as Standard form (SF), Slope – intercept form (SI), or Neither (N) 1.4x + 3y = 8 2.9x – 4 = 5 3.Y = 4x Y = 2x 5.X = 8
