Answer 1

Answer:

(-1 / 4)x + y = -1.75

Step-by-step explanation:

Standard form is Ax + By = C

First I'm going to write it in point slope form, then I'm going to simplify.

Slope: (-3 + 1) / (-5 - 3) = 1 / 4

(y + 1) = 1 / 4(x - 3)

y + 1 = x / 4 - 3 / 4

(-1 / 4)x + y = -1.75

This might be wrong because I don't really like to use standard form.

Answer 2

Answer:

x-4y =7

Step-by-step explanation:

First find the slope

m = (y2-y1)/ (x2-x1)

    = (-3--1)/(-5 -3)

   = (-3+1)/(-8)

  -2/-8

    1/4

Using slope intercept form

y = mx+b

y = 1/4x+b

substituting a point into the equation

-1 = 1/4(3) +b

-1 = 3/4+b

-1 -3/4 =b

-7/4 =b

y = 1/4 x -7/4

Multiply by 4

4y = x-7

subtract x from each side

-x+4y = -7

Multiply by -1

x-4y =7

The standard form of a line is

ax +by =c

where a is a positive integer , b and c are integers
