Question

Indicate in standard form the equation of the line passing through the given points.

B(0, 0), C(4, -4)

Answer 1

x+y=0

Answer 2

but that cant be the answer

Answer 3

Never mind that is the correct answer but could i get how u got that

Answer 4

calculate the slope:y-y0/x-x0
put in y=mx+c where m is slope.and if my answer is not right maybe its because of c i assumed it to be 0.

Answer 5

m = (y2 - y1)/(x2 - x1)....set 1 (0,0)...set 2 (4,-4)
m = (-4 - 0)/ (4 - 0)
m = -4/4 = -1

y = mx + b ....using points (4,-4)
-4 = -1(4) + b
-4 = -4 + b
-4 + 4 = b
0 = b

y = -1x + 0

ax + by = c
-x + y = 0

You might better get a second opinion on this
