Question

Answer the following question:

Find the equation of the line having slope 5 and containing point A(–1, 2).

Answer 1

Given, slope(m) = 5 and the line passes through A(–1, 2).

Equation of the line in slope point form is y – y₁ = m(x – x₁)

∴ The equation of the required line is

y – 2 = 5(x + 1)

∴ y – 2 = 5x + 5

∴ 5x – y + 7 = 0
