Question

What equation in slope intercept form represents the line that passes through the two points? (2, 5), (9, 2) A. y = 3/7x -41/7 B. y = -7/3x -41/7 C. y = 7/3x +41/7 D. y = -3/7x + 41/7

Answer 1

m = (y2-y1)/(x2-x1)

m = (2-5)/(9-2)

m = -3/7

passing (2, 5),

y = mx + b

5 = -3/7(2) + b

b = 5 +6/7

b = 41/7

equation

y = mx + b

y = -3/7x +41/7

answer: D. y = -3/7x + 41/7
