WRITING THE EQUATION OF A LINE
2
Slope intercept form of a line

• Y mx b
• b is the y-intercept point where it intersect
  the y axis.
• m is the slope of the line. Rise over run.

Steps to follow

• Ymx b
• Find where the line intersects the y-axis, put
  that number in the b spot of the equation.
• Decide if the slope is positive or negative, put
  that in front of the x leaving room for a number.
• Draw a right triangle on the line. It must go
  thru an exact corner. This triangle will help
  identify the rise and the run of the line.
• Write the number for the slope in lowest terms.
