Step-by-step explanation:
parallel lines have the same gradient..
y=x+7 has a gradient of 1.
If line J which is parallel to k has a gradient of 1 then they are the same.
gradient (m) =<u>∆</u><u>y</u>
∆x
=<u>y- </u><u>-</u><u>1</u><u> </u> = 1
x - - 3
= <u>y </u><u>+</u><u> </u><u>1</u>
x+3
y+1=x+3
y=x +3 +1
y = x + 4(equation for k)
Multiply all terms by the common denominator which is 15
