i have one more after this

welshfella · Answer

slope of the required line = -1/-1

welshfella · Answer

call this slope m 

then use  y - y1 = m(x-x1)  to find its equation

triciaal · Answer

@welshfella slope of the required line = -1/0  so m = 0
@rayep12 use the formula given by @welshfella your (x1, y1) is the point (8, -4)

welshfella · Answer

OH Yes  Sorry  that was a mistake.  The slope of the line y = -1  is not -1!!!

welshfella · Answer

in fact the slope of the line  we need to find  is infinite so its a vertical line

welshfella · Answer

passing through  (8,-4)

welshfella · Answer

you dont need to use the formula I gave

triciaal · Answer

@rayep12   do you know how to find the slope of a line?
can you find the equation of the line using the formula given?
do you need more help? any questions?  don't know where you are and you provide some input?
