Use the formula for slope to verify that a horizontal line has a slope of zero and that a vertical has an undefined slope.
I have no idea what to do can some one help explain it to me thanks. :)

The slope of the line through points (x1,y1) and (x2,y2) is given by : \(\huge m=\frac{y_1y_2}{x_1x_2}\) now horizontal line has equation of the form y=c, here xterm has '0' coefficient take any two points on this, say (x1,c),(x2,c) so put y1 = c and y2 = c in m and tell me what u get.

i'll draw a horizontal linedw:1348817053391:dw can u see that yco ordinate of every point on that line is same??

that means for any value of xcoordinate , y coordinate will be some constant 'c' only.....so we can write its equation as y=c got this?

i think so the y will stay the same ( constant) meaning y = c ??

yup. similarly for vertical line , the equation is x=c

for a vertical line, x coordinate always remains constant. hence its equation can be written as x=c did u understand this?
