Line Equation from Two Points

Verdich [7]

Hi!

We can use point-slope form to solve this.

$y-y_{1} =m(x -x_{1})$

$y_{1}$ and $x_{1}$ will be from one of the points.

First, we have to find $m$ , the slope. We can use the slope equation to get this.

$\frac{y_{1} -y_{2} }{x_{1} -x_{2} }$

Plug in your points:

$\frac{4-0}{8-(-8)} =\frac{4-0}{8+8} =\frac{4}{16} =\frac{1}{4}$

Your slope is $\frac{1}{4}$

Now plug points and slope into point-slope equation. We will use (8, 4).

$y-4=\frac{1}{4} (x-8)$

Now, if you want to get it into y = mx + b form, you have to solve for y:

$y-4=\frac{1}{4} (x-8)$

$y-4=\frac{1}{4} x-2$

$y=\frac{1}{4} +2$

Your equation is $y=\frac{1}{4} +2$

Please help me I really need help I’m gonna give 33 points for this please help

lidiya [134]

Answer:

Step-by-step explanation:

1a) use letter "P" for perimeter

1b) use letter "L" or "x"

1c) Formula: P=4L or P=4x

2) the formula for the perimeter of a square is P=4L or P=4x because to find the perimeter you have to add up all the sides, and for a square, all the sides are equal, so it is P=4L or P=4x.
