Question

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

x + y = −4

x + y = 4

x − y = −4

x − y = 4

Answer 1

write it in slope-intercept form first

Answer 2

then, convert it to standard

Answer 3

scratch that,
write it in point-slope form first

Answer 4

point : (−2, 6)
slope : −1

Answer 5

point slope form :-
y-y1 = m(x-x1)

Answer 6

y - 6 = -1(x- 2)

Answer 7

care ful of signs,
its -2

Answer 8

y-6 = -1(x--2)

y-6 = -1(x+2)

y-6 = -x - 2

x+y = 4

Answer 9

alight i got it

Answer 10

thanks man
