Writing Equations in
Point-Slope Form
Section 4.3 pages 233-238
𝑦 βˆ’ 𝑦1 = π‘š(π‘₯ βˆ’ π‘₯1)
Point – Slope Form
Write an equation of the line in Point-Slope form
through the point 3, βˆ’2 with the slope of
1
4
.
Given the line 𝑦 βˆ’ 7 = βˆ’
3
4
(π‘₯ + 5)
find the slope and a point on the line.
Given the line 𝑦 βˆ’ 5 =
4
3
(π‘₯ βˆ’ 3)
write the line in Slope Intercept Form.
Given two points on a line 4,2 π‘Žπ‘›π‘‘ (7,5)
Find the equation of the line in Point-Slope Form.
Find another equation of the same line in Point-Slope Form.
Recall
Slope π‘š =
𝑦2 βˆ’ 𝑦2
π‘₯2 βˆ’ π‘₯1
Slope Intercept Form 𝑦 = π‘šπ‘₯ + 𝑏
Point Slope Form 𝑦 βˆ’ 𝑦1 = π‘š(π‘₯ βˆ’ π‘₯1)
