Question

.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?

Answer 1

do you know how the first line would look like??

Answer 2

1) (5,0) and (5,1) as x=5 (for y part write any real value)
2) (0,-2) and (1,-2) as y=-2(for(x part write any real value)

Answer 3

horizontal line is always y= something. in this case its y = -8 because the line crosses the y axis there. (it also crosses the x axis at -1 at this point, but since its a horizonal line then this is irrelevant)

same applies to the second part of the question but with the y axis this time... x = 3

from the above you should be able to work out whether the next two are horizonal or vertical. :)

Answer 4

Thank you (:
