Question

Write an equation in slope intercept form of the line that passes through (4, 1) and (5, -1).
A. y = -4x + 1
B. y = -1/2 x + 9
C. y = 4x + 1
D. y = -2x + 9

Answer 1

use m = y2 - y1 / x2 - x1 to find slope and then substitute the x and y values (any coordinate ) and then u find b from that

Answer 2

trying plugging in the value (4,1) and (5,-1) in all equations.......the one which satisfies the equation with both values is your answer
