• (0,3)

Write the equation for the line.

• y= -1x+3
• y= 4x+3
• y=1/4x+3
• y= -4x+3

What is the y-intercept in the following equation:  y=-4x-5

• -4

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.
