Write equations of the horizontal and the vertical lines that pass through the point (7,-9).

y = - 9 and x = 7

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

where c is the value of the y- coordinates the line passes through

The line passes through (7, - 9) with y- coordinate - 9 , then

y = - 9 ← equation of horizontal line

The equation of a vertical line parallel to the y- axis is

x = c

where c is the value of the x- coordinates the line passes through

The line passes through (7, - 9) with x- coordinate 7 , then

x = 7 ← equation of vertical line

cells do need food. in a process known as cellular respiration, cells convert biochemical energy (oxygen as food) from nutrients into adenosine triphosphate (atp), and then release waste products.
