Question

Find the equation of the line through the point (1, -5) and || to the x-axis.

Answer 1

y+5=0

Answer 2

how did you do it?

Answer 3

Please explain.

Answer 4

It goes through the value of -5 and since it needs to be parallel that means that the line has to be a horizontal line and the only way to write a horizontal line is y= number
in this case it is y=-5 or y+5=0 (same line)

Answer 5

parallel to x axis means constant value of y.
so, y=-5
y+5=0

Answer 6

its parallel to x axis
u can say the equation is y=k
putting the value of y k=-5
so,the equation is y=-5

Answer 7

Sometimes it is easy to use graph paper and actually see what the point looks like and then draw in the line. Eventually you would have seen that you needed a horizontal line.
