Determine the slope and y-intercept from the following equation:   y = 3/2x + 3

• slope: 5   y-intercept:  (0,3) 

• slope: 3/2   y-intercept:  (0,3) 

• slope:  4  y-intercept:  (0,3/2)

• slope: 1/5   y-intercept:  (0,5) 

The y intercept is AWESOME! It helps us to know...

• Where our line will end.

• If our line is positive or negative.

• Where to start graphing our line.

Find the slope and y - intercept

• slope: 1/2 y-intercept: -1

• slope: 2 y-intercept: -1

• slope: 1/2x y-intercept: 1

• slope: 2 y-intercept: 5

In the equation, y = mx + b, the letter b is the ___________.

• y-intercept

• x-intercept

• slope

• rate of change

Consider the equation:
y=-x+4
Identify the slope and y-intercept.

• m=4, b=-x

• m=-x, b=4

• m=1, b=4

• m=-1, b=4
