Give the coordinates of two points on the line x = 5. Give the coordinates of two points on the line y = -2. Write the equation of the horizontal line passing through the point (-1, -8). Write the equation of the vertical line passing through the point (3, 1). Is the line with equation x = 4 horizontal or vertical? What is the slope of this line? Is the line with equation y = -8 horizontal or vertical? What is the slope of this line?

    5,1 and 5,2 are on the line x=5 9,-2 and 10,-2 are on the line y=-2 Do you understand why?

    -Give the coordinates of two points on the line x = 5.--->This is a vertical line, so any y value would work. Ex. (5, 1), (5, 2), (5, 3).... and so on. Give the coordinates of two points on the line y = -2.----> This is a horizontal line, which means any x value can be changed. Ex (1, -2), (2, -2), and so on.

    sorry it got cut off. It means basically, when you first point x=5, it is a vertical line going through 5,0 and covering the whole y axis. So y can be any values.

    Write the equation of the horizontal line passing through the point (-1, -8).--->You are told that this is a horizontal line, Which means that the x values change, but the y values do not change, So you can write y=-8 Write the equation of the vertical line passing through the point (3, 1).---->This is vertical which means the y values only change, and not the x values, So you can write x=3

    Is the line with equation x = 4 horizontal or vertical? What is the slope of this line? ----> This line would be a vertical line, Every vertical line has an "undefined slope" Is the line with equation y = -8 horizontal or vertical? What is the slope of this line? ---->This is a horizontal line, every horizontal line has a "slope of 0"

    Is the line with equation x = 4 horizontal or vertical? What is the slope of this line? It is vertical. Just like the example I drew up there. The slope is "No Slope" you can see this. It doesn't slope!

    @tumblrfanatic Horizontal lines have no slope. Vertical lines have undefined slopes.

    @zordoloom Don't horizontal lines have a slope of 0. Just 0 . And vertical lines have no slope. / infinity. That's what I was taught.

    @tumblrfanatic That is correct, Horizontal lines have no slope, same as slope of 0, But vertical lines have an undefined slope. There is not infinity involved. I'm pretty sure you meant the same thing, probably worded differently.

    @zordoloom Ah yes. I see. I called a vertical line no slope.
