If a line has a slope of 4 and contains the point (-2, 5), what is its equation in

point-slope form?
A. y-5= 4(x + 2)
B. y-5= 4(x-2)
OC. y+ 2 = 4(x-5)
OD. y + 5 = 4(x - 2)

Answer: A. y - 5 = 4(x + 2)


\rule{130}{1}


\rule{1}{5 } \ \ \sf point \ slope \ form : y-y_1 = m(x - x_1) \quad \ where \ (x_1 , \ y_1)\ are \ points \ \ \ \rule{1}{5}

Given points: (-2, 5)

solving stepwise:


\rightarrow y - 5 = 4(x - (-2))


\rightarrow y - 5 = 4(x +2) \bf \quad \quad This \ is \ point \ slope \ form


\rightarrow y - 5 = 4x + 8


\rightarrow y = 4x + 13 \quad \quad \quad \quad \bf This \ is \ slope \ intercept \ form
