Question

Any line with an undefined slope is parallel to the

a.x-axis
b.y-axis
c.line y = x

Answer 1

\[\huge\rm \frac{ y_2 -y_1}{ x_2 -x_1 }=m\] formula to find slope
when will you get undefined slope ??

Answer 2

when you have same x or same y values ??
x= number ( vertical line)
y= number (horizontal line )

Answer 3

so y=x

Answer 4

y=mx+b is same as y=mx+0
where m is slope and b represent y-intercept

Answer 5

im sorry, i dont get it i suck at this:(

Answer 6

when would be the fraction undefined ??
if you have 0/a or a/0 ?

Answer 7

o/a i think

Answer 8

well you can divide 0 by a number
but you can't divide anything by 0 can you >??

Answer 9

\[\large\rm \frac{ anything }{ 0 }=undefined \]

Answer 10

\[\huge\rm \frac{ y_2 -y_1}{ x_2 -x_1 }=m\]
formula to find slope
this fraction representt the slope formula
in order to get undefined slope you need same x values so when you subtract them you will get 0
like 2-2 , 3-3

Answer 11

so it was c?

Answer 12

now draw a line on the graph
http://prnt.sc/aa3eue
y values are constant when you draw horizontal line
and the x values would be constant when we draw vertical lines (that will give you undefiend slope )

Answer 13

y=x is same as y=1x which is same as y=mx where m is the slope

Answer 14

oooo yhanks i get it know

its y- axis right?
