Question

find the equation of the straight line which passes through (2,-3) and is. (1) parallel to x-axis. (2) parallel to y-axis​

Answer 1

Answer:We have 2 cases:

Case (1):

passes through (2,-3) and parallel to x-axis,

Parallel to x-axis means that the slope = 0

==> y-y1= m(x-x1)

==> y+3 - 0

==> y= -3

Case 2:

Passes through  (-2, 3) and parallel to y-axis,

That means that the function does not intersect with y-axis then y values are unlimited:

Then the equation is:

==> x= -2
