Question

What is the slope of the line represented by the equation y = 7?

Answer 1

the equation for slope is
\[m = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]
and for a line y = 7 no matter what x you take the y value remains the same so you will always get
\[\frac{ 7-7 }{ x _{2}-x _{1} } =\frac{ 0 }{ x _{2}-x _{1} } \]
and zero divided by any number is still zero

Answer 2

\[\frac{ \Delta y }{ \Delta x }\]

Answer 3

What is the slope of the line represented by the equation x = -9?

this is the last one

Answer 4

The slope of the line is undefined...there is only one x- value for an infinite amount of y values,

Answer 5

thankyou! thats the answer i thought it was, I just wanted to make sure.

Answer 6

would anyone mind helping me on a few more?

Answer 7

@Eleven17 No an undefined slope is the equation x = 7 because you divide by zero when calculating the slope and any number divided by zero is undefined (infinite)
when zero is divided by a number the answer is still zero not undefined thus the slope can still be calculated

Answer 8

@itsjustme_lol yes just close this question and post the next one as a new question

Answer 9

thanks
