Answer 1

Answer: The required equation of the line in standard form is
`4x-3y=5.`

Step-by-step explanation: We are given to write the standard form of the line that passes through the points (-1, -3) and (2, 1).

We know that

the slope of a line passing through the points (a, b) and (c, d) is given by

`m=(d-b)/(c-a).`

So, the slope of the given line is

`m=(1-(-3))/(2-(-1))=(4)/(3).`

Since the line passes through the point (2, 1), so its equation will be

`y-1=m(x-2)\\\\\Rightarrow y-1=(4)/(3)(x-2)\\\\\Rightarrow 4x-8=3y-3\\\\\Rightarrow 4x-3y=5.`

Thus, the required equation of the line in standard form is
`4x-3y=5.`
