Question

Using the slope and the y-intercept, graph the line represented by the following equation. Then select the correct graph. 2y + 4 = 0

Answer 1

Hello there!

2y + 4 = 0

2y = -4

y = -2

My assumption is that you'd graph this as a horizontal line at (0,-2) but PLEASE double check with your teacher/instructor because I'm not sure if I'm right.

Hope this helped!

Answer 2

Answer:

A line parallel to x axis and passing through (0,-2)

Step-by-step explanation:

Let us see the slope intercept form of a linear equation.

It is given as

y=mx+c

Our equation is

2y+4=0

Or 2y+0*x+4=0

2y=0*x-4

Dividing each term by 2 we get

y=0*x-2

Comparing it with

y=mx+c

m=0, that is slope of line is 0, or we can say that the line is parallel to x axis.

Also

c=-2

That means this line intersect at (0,-2) on y axis.

Hence it is a line parallel to x axis and intersecting y axis at (0,-2)
