Question

Point (-1,3). m= Undefined.

Find the equation of the line that contains the given point and has the given slope.
And explain..

Answer 1

m=1/0 (undefined)

equation=y2-y1/x2-x1=y-y1/x-x1

since M is undefined and M=y2-y1/x2-x1

then the equation=y-y1/x-x1=1/0

y-3/x--1=1/0

cross multiplying

0 (y-3)=1 (x+1)

=x+1
