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 ..

step-by-step explanation:

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
