Question

1. Give the coordinates of two points on the line x = 5

2. Give the coordinates of two points on the line y = -2.

3. Write the equation of the horizontal line passing through the point (-1, -8).

4. Write the equation of the vertical line passing through the point (3, 1).

5. Is the line with equation x = 4 horizontal or vertical? What is the slope of this line?

6. Is the line with equation y = -8 horizontal or vertical? What is the slope of this line?

Answer 1

1)5,0 &5,1
2)

Answer 2

for question one. look at the equation it say x = 5 so lets try to graph this.. well we need a y coordinate too to be able to graph the line so lets just pick any number lets say "2" now we have:
x=5
y=2
now plug in y to find your x coordinate ! notice how there is no y so we cant plugin our y anywhere is x = 5 and y =2
so our first coordinates are (5,2) and you can repeat this process with the rest of the problems !
