Answer:

See the picture below

Explanation:

Your equations are in the slope-intercept form of a line. The equations are make up of a slope and a y-intercept.

y = mx + b The m is the slope (the steepness of the line) and b is the y-intercept. This is where the line crosses the y axis.

I would start with the y intercept. Look at the first equation

y = x -8 The -8 tells us that this graph crosses the y axis at (0,-8) From that point, we will use the slope. The slope is the number before the x. If we do not see a number than it is 1. We want to make this a fraction. What is 1 as a fraction? 1/1 This means that from -8 where the graph crosses the y axis we will follow the pattern of up one, one to the right.

Let's look at the second graph

y = -x + 5. This tells us that we cross the y axis at (0,5). Our slope is -1. What is -1 as a fraction? -1/1. This means that we will move down 1 and right one. We will follow that pattern.

Let's look at the third graph

y = 3/4x - 1 We cross the y axis at (0,-1) From that point we move up 3 and right 4.

y = 3 means that no matter what x is, y will be -3. This creates a horizontal line.

x = -4 means that not matter what y is, x will be -4. This creates a vertical line.
