4# Vertical line is x = 3
5# Horizontal line is y = 7
10# Slope of the line = (-7-8)/(-1-(-4))
= -15/3 = -5
11# Slope of the line = (-3 -5)/(2-2) = -8/0 = infinite, ie the line is parallel to y axis
12# Slope of the line = (-9-(-9))/ ( 0 - (-4)) = 0/4 = 0, ie the line is parallel to x axis
15# 8x - 2y = 4
or, x/0.5 - y/0.5 = 1
or, x/0.5 + y/(-0.5) = 1
Therefore x intercept is 0.5 or 1/2 and y intercept is -0.5 or -1/2
16# y = - 4x + 8
or, 4x + y = 8
or, x/0.5 + y/8 = 1
Therefore x intercept is 0.5 or 1/2 and y intercept is 8
Hope it helps.
Thanks you..!!
