2.  When given a table of data related to a straight line, writing the equation of the line in slope-intercept form is very straight forward.

3. Find the equation matching the table shown below and put it in slope-intercept form. xy 01 13 25 37

4. xy 01 13 25 37 (x 1, y 1 ) (x 2, y 2 ) You can use these two points to calculate the slope of the line.

5. Substitute in values. Simplify Slope

6. Substitute in value for slope and simplify

7. y-intercept Substitute in values for a point Simplify

8. Substitute in value for y-intercept and simplify Equation for the line is in slope-intercept form
