Question

Line the slope and y-intercept to graph each equation below

Answer 1

The graphs in the attachments.

Explanation:

The slope-intercept form of an equation of a line:

`y=mx+b`

m - slope

b - y-intercept

We have the equations of the lines in the general form Ax + By + C = 0.

Convert to slope-intercept form:

8.

`2x-2y+5=0` subtract 2x and 5 from both sides

`-2y=-2x-5` divide both sides by (-2)

`y=x+(5)/(2)`

9.

`y-3=0` add 3 to both sides

`y=3`

8.

To draw a line we need only two points. Choice any two x values ​​and calculate the y values.

`for\ x=0\to y=0+(5)/(2)=(5)/(2)=2.5\to(0,\ 2.5)\\\\for\ x=-2\to y=-2+(5)/(2)=-2+2.5=0.5\to(-2,\ 0.5)`

9.

`y=3`

It's a horizontal line.
