Answer :
Given the points ( -7 , 4 ) and (-7 , -3 )
The slope of the line passing through the given points is calculated as following :
[tex]slope=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}=\frac{-3-4}{-7-(-7)}=\frac{-7}{-7+7}=-\frac{7}{0}=0[/tex]So, the slope of the line = 0
which mean the line will be parallel to the x- axis
