Question

Which is an equation of the given line in standard form? A. –11x + 6y = –13 B. –6x +11y = 13 C. –6x + 11y = –13 D. –6x + 7y = –17

Answer 1

(1 1/2,2) x1 = 1 1/2 or 3/2 and y1 = 2
(-4,-1) x2 = -4 and y2 = -1
find the slope..
slope(m) = (y2 - y1) / (x2 - x1) m = (-1-2) / (-4 - 3/2)
m = -3/(-8/2 - 3/2
m = -3/(-11/2)
m = -3 * -2/11
m = 6/11
y = mx + b
-1 = 6/11(-4) + b
-1 = - 24/11 + b
-1 + 24/11 = b
- 11/11 + 24/11 = b
13/11 = b y = 6/11x + 13/1
11y = 6x + 13 -6x + 11y = 13
so option B is correct
hope it helps
