Writing point-slope forms to satisfy given conditions

Question

Write the point-slope form of the line's equation satisfying the given conditions. Then use the point-slope form of the equation to write the slope-intercept form of the equation in function notation.

Slope = 4, passing through (2,6)

Answer 1

y - y₁ = m(x - x₁)

y - 6 = 4(x - 2)

Solve for y (= f(x))

Answer 2

Use point-slope form. It should be demonstrated in your text book.
