Question

find the equation of a line that passes through the point (5,-4) and if perpendicular to the equation x=-4

Answer 1

is*

Answer 2

Since it is perpendicular, the slope of this line should be the negative reciprocal of the line x=-4. Do you know how to do this?

Answer 3

yes, thats when you do the opposite. so it would be 4/1?

Answer 4

the equation i got is y=4x+5 is that right?

Answer 5

Wait are you sure this is the correct problem? This is a vertical line, which has an undefined slope.

Answer 6

yes, i just checked it is. so what happens if its a undefined slope?

Answer 7

You can't fined the negative reciprocal if the slope is undefined.

Answer 8
