Answer:

  y -1 = -1(x -2)

Step-by-step explanation:

The slope of the line through the two points can be found from the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (5 -1)/(-2 -2) = 4/-4 = -1

The point-slope equation for a line through point (h, k) with slope m is ...

  y -k = m(x -h)

You have (h, k) = (2, 1) and m = -1. Putting these values into the form gives ...

  y -1 = -1(x -2)

_____

<em>Additional comment</em>

Your problem statement already has two of the three values filled in, so you only need to enter the x-coordinate of the first point: 2.

Put the equation in standard form with a positive x coefficient. 2y+5=-4(x+2)
umka21 [38]

The standard form of equation is: 4x+2y = -13

Step-by-step explanation:

the standard form of a linear equation in two variables is given by:

ax+by = c

Given equation is:

2y+5=-4(x+2)

Distributing -4 into the round bracket

2y+5 = -4x-8

Adding 4x on both sides

4x+2y+5 = -4x-8+4x\\4x+2y+5 = -8

subtracting 5 from both sides

4x+2y+5-5 = -8-5\\4x+2y = -13

The standard form of equation is: 4x+2y = -13
