Thank you for the opportunity to help you with your question!

a)We have the equation of the line as y=6,

x-intercept:-It is the value of x where the line crosses the x -axis.As the line is parallel to x axis and never crosses it therefore the x-intercept is not defined.

x-intercept=>Not available

y-intercept:-It is the value of y,where the line crosses the y-axis.As it is a line parallel to the x aixs and it crosses the y-axis at y=6

therefore the y-intercept is 6

Ordered pair is (0,6)

Slope of the line is 0 as it is parallel to the x -axis.

b)For the line x= -4

As it is perpendicular to the x axis therefore the slope of the line is not defined.

X-intercept-.It crosses the x-axis at -4.

Ordered pair is (-4,0)

y-intercept:It never crosses the x-axis therefore the y-intercept is not available.
