PLEASE HURRY!!

What is the equation of a line that passes through (-6, 2) and has a slope of `-(1)/(2)` ?

A. y=(x)/(2)-2
B. y= -(x)/(2)-1
C. y=2x+1
D. y= -2x-1

Answer 1

B

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 = -
`(1)/(2)`, thus

y = -
`(1)/(2)` x + c ← is the partial equation

To find c substitute (- 6, 2) into the partial equation

2 = 3 + c ⇒ c = 2 - 3 = - 1

y = -
`(1)/(2)` x - 1 → B

Answer 2

B. y= -(x)/(2)-1
