Question

Choose the equation below that represents the line that passes through the point (4,9) and has a slope of 7. y - 9 = 7(x - 4) y + 4 = 7(x + 9) y - 4 = 7(x - 4) y + 9 = 7(x + 4)

Answer 1

Answer:

y - 9 = 7 (x - 4)

Explanations:

The equation of a line which has a slope, m, and passing through the point (x₁, y₁) is given as:

y - y₁ = m (x - x₁)

The line described in this question passes through the point (4, 9) and has a slope, m = 7

x₁ = 4, y₁ = 9

Substituting the values of x₁, y₁, and m into the equation above:

y - 9 = 7 (x - 4)
