Could you please show me how to do this.

Write an equation of the vertical and horizontal lines that pass through the given point (6,-6)

y equals?
x equals ?

3 answers

You'll use the fourth quadrant, count to six on the X Axis and then count to -6 on the Y Axis.

Plot your point.
the equation of a horizontal line looks like y = c
the equation of a vertical line looks like x = k, where c and k are constants.

in your case:
y = -6
x = 6
Ok, I get it now, thanks!
