In this lesson, we will learn how to find the equation of a line in the form 𝑦 – 𝑦₁ = 𝑚(𝑥 – 𝑥₁) or 𝑎𝑥 + 𝑏𝑦 + 𝑐 = 0 given the slope and one point, or two different points, that it passes through.

Students will be able to

Q1:

Find the equation of the straight line passing through the points (1,5) and (4,11).

Q2:

The line π¦=4π₯β8 crosses the π₯-axis at the point π΄. Find the equation of the line with a slope of β3 passing through the point π΄.

Q3:

The lines π¦=2π₯+1 and π¦=βπ₯+4 intersect at the point π΅. Find the equation of the line with a slope of 12 that passes through the point π΅.
