1. Writing Equations of Lines
Point Slope Form

2. Write the equation of the line with slope 3 and passing through the point (1, 5).
Use Point-Slope Form
y – y1 = m(x – x1)

3. Write the equation of the line with slope ¾ and passing through the point (-5, 3).
Use Point-Slope Form
y – y1 = m(x – x1)

4. Write the equation of the line with slope -2/3 and passing through the point (2, -4).
y – y1 = m(x – x1)

5. Find the slope let's use (3, -1)
