Write an equation in slope intercept form of the line that passes through (4, 1) and (5, -1).

Answer 1

y-y1=m(x-x1)
-1-1=m(5-4)
M=-2

Answer 2

Olivia found the slope

so y = -2x + b
sub in one of the given points, I will use (4,1)
1 = -2(4) + b
b = 9

y = -2x + 9

(test it with the other point, it works)
