The vertices of a triangle are A(-2, 1), B(2, 2) and C(6, - 2). Find the equation of the altitude of AD drawn from A to BC.

The equation of altitude AD drawn from A to BC will be:

Step-by-step explanation:

Let m₁ and m₂ be the slope of line AD and BC respectively.

Now, AD⊥BC

∴ m₁ × m₂ = -1

be the slope of line AD and BC respectively.

⇒ m₁ = -1/m₂    → (A)

Finding the slope of BC using points

B(2, 2)

C(6, - 2)

On substituting the value of m₂ in equation (A)

m₁ = -1/m₂

    = -1/(-1)

    = 1

We know that the point-slope form of the line equation is

∴ Equation of altitude AD passing through A(-2, 1) with slope 1 will be

Therefore, the equation of altitude AD drawn from A to BC will be:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
