I need some help on my math test!!, I get to retake it but I need help with some of it:

Write the Equation of the line that passes through the point (-4,-9) and has a slope of 1/2

Choices:
Y=1/2x–7
Y=1/2x+7
Y=1/2x+11

Respuesta :

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{1}{2}[/tex], thus

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (- 4, - 9) into the partial equation

- 9 = - 2 + c ⇒ c = - 9 + 2 = - 7

y = [tex]\frac{1}{2}[/tex] x - 7 ← equation of line
