Question

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

Answer 1

Answer:

The graphs in the attachments.

Step-by-step 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)

$y=x+\dfrac{5}{2}$

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.

$for\ x=0\to y=0+\dfrac{5}{2}=\dfrac{5}{2}=2.5\to(0,\ 2.5)\\\\for\ x=-2\to y=-2+\dfrac{5}{2}=-2+2.5=0.5\to(-2,\ 0.5)$

9.

$y=3$

It's a horizontal line.
