Question

HELPPPP QUICKWhich equation in slope-intercept form represents a line that is parallel to y = 1/2x-2

and passes through the point (-8, 1)?
A y = -2x-7
B y= 1/2x+5
C y= -2x-5
Dy=-1/2x+5
E y= 1/2x-9

Answer 1

B

Explanation:

the general slope intercept form is

y = ax + b

a is the slope, b is the y-intercept (the y value when x = 0).

a parallel line must have the same slope (1/2).

for b we simply put the x and y values of the given point into the equation

1 = 1/2 × -8 + b = -4 + b

b = 5

therefore,

y = 1/2 x + 5

is the correct solution.
