A line passes through (−1, 5) and (1, 3).

Which answer is the equation of the line?

d) x+y = 4

Step-by-step explanation:

(−1, 5) and (1, 3)

y = mx + b

m = (3 - 5) / (1 - (-1)) = -2 / 2 = -1

b = y - mx = 3 - ((-1) x 1) = 4

equation:  y = -x + 4

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
