A line passes through (10,2) and (14,-22). Write the equation of the line in standard form.

Sagot :

Answer:

The equation of the line in standard form is:

[tex]6x + y = 62[/tex]

Step-by-step explanation:

Given the points

  • (10,2)
  • (14,-22)

Determining the slope between (10, 2) and (14, -22)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(10,\:2\right),\:\left(x_2,\:y_2\right)=\left(14,\:-22\right)[/tex]

[tex]m=\frac{-22-2}{14-10}[/tex]

[tex]m=-6[/tex]

The point-slope form of the line equation is  

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

  • m is the slope of the line
  • (x₁, y₁) is the point

substituting the values m = -6 and the point (10, 2) in the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 2 = -6(x - 10)[/tex]

[tex]y - 2 = -6x +60[/tex]

adding 2 to both sides

[tex]y-2+2 = -6x + 60 + 2[/tex]

[tex]y = -6x + 62[/tex]

We can write the equation in the standard form such as

Ax + By = C

Thus,

[tex]y = -6x + 62[/tex]

adding -6x to both sides

[tex]6x + y = -6x + 62 + -6x[/tex]

[tex]6x + y = 62[/tex]

Therefore, the equation of the line in standard form is:

[tex]6x + y = 62[/tex]
