Question

What is the equation in standard form of the line which passes through (–2, 6) and has a slope of –1?

Answer 1

– y = –4
x + y = 4
x – y = 4
x + y = –4

Answer 2

y=-x+q with undefined q, put then the x and y of the point here....
6=2+q so q=4
finally the eqution will be y=-x+4

Answer 3

xD in this case solution is the second one ;)
