Question

Write an equation in point-slope form of the line that passes through the point (2, 1)

and has a slope of m=2
.

Answer 1

• y - 1 = 2(x - 2)

-----------------------

Point-slope form is:

• y - y₁ = m(x - x₁), where, m is the slope and (x₁, y₁) is the point on the line

Substitute the given into equation:

• y - 1 = 2(x - 2)
