Choose the equation that represents a line that passes through points (−1, 2) and (3, 1).
a. 4x − y = −6
b. x + 4y = 7
c. x − 4y = −9
d. 4x + y = 2

B. x + 4y = 7

Step-by-step explanation:

There are two points given:

(-1, 2) and (3, 1)

The standard form of equation is:

y = mx+b

We have to find the slope first

So,

y = (-1/4)x + b

We have to find the value of b

1 = (-1/4)(3) + b

1 = -(3/4) + b

1 + (3/4) = b

7/4 = b

Putting the values of b and m in standard equation

Hence, option B. x + 4y = 7 is correct ..

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
