Write the equation of the line in stasndard form that passes through the points 2,-3 and -1,-4

Answer 1

slope = m = (-4+3)/(-1-2)
= -1/-3 = 1/3

-3 = (1/3)(2) + b

b = -9/3 - 2/3 = -11/3

y = (1/3) x -11/3

3 y = x - 11

x -3 y = 11

Answer 2

I don't understand how you worked to get the y intercept.

Answer 3

I knew the slope m
so I used y = m x + b
I put in 2 for x and -3 for y
that is the point (2,-3)
-3 = (1/3)(2) + b
