Determine the standard form of the equation of the line that passes through (-2, 0) and (-8,5)

Naya [18.7K]

Answer:

$-5x-6y=10$ ← in standard form

Step-by-step explanation:

The equation of a line in standard form is.

$Ax+By=C$

were

A is a positive integer and

B, C are integers

As the equation in point-slope form

$y-y_1=m\left(x-x_1\right)$

where m is the slope and $\left(x_1,\:y_1\right)$ is a point on the line.

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-2,\:0\right),\:\left(x_2,\:y_2\right)=\left(-8,\:5\right)$

$m=\frac{5-0}{-8-\left(-2\right)}$

$m=-\frac{5}{6}$

using $m=-\frac{5}{6}$ and $\left(x_1,\:y_1\right)=\left(-2,\:0\right)$ then

$y-0=-\frac{5}{6}\left(x-\left(-2\right)\right)$

$-\frac{5}{6}\left(x-\left(-2\right)\right)=y-0$

$6\left(-\frac{5}{6}\left(x-\left(-2\right)\right)\right)=6y$

$-5\left(x+2\right)=6y$

$-5x-10=6y$

$-5x-6y=10$ ← in standard form

Answer:

x = -5/2

Step-by-step explanation:

4x+2 = -8

We are solving for x

The first step in isolating x is to subtract 2 from each side

4x+2-2 = -8-2

4x = -10

Divide each side by 4

4x/4 = -10/4

x = -10/4

Simplify the fraction

x = -5/2
