Question

What is the equation of the line that passes

through point (0, -1) and is parallel to
y = -2x + 3?

Answer 1

y = - 2x - 1

Explanation:

The equation of a line in slope- intercept form is

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

y = - 2x + 3 ← is in slope- intercept form

with slope m = - 2

Parallel lines have equal slopes

The line passes through (0, - 1 ) ⇒ c = - 1

y = - 2x - 1 ← equation of parallel line

Answer 2

y=-x/2-1

Explanation:

-2=x-0/y+1

(y+1)-2=x-0

-2y-2=x-0

-2y=x-0+2

-2y/-2=x/-2+2/-2

y=-x/2+(-1)

y=-x/2
