Given that Line A goes through points (-4,5) and (8,8). Write an equation of a line that is parallel to Line A, and goes through point: (-12,-10).

Respuesta :

Answer:

[tex]y + 10 = \frac{1}{4 } (x + 12)[/tex]

Or

[tex]y =\frac{1}{4 } x -7[/tex]

Step-by-step explanation:

We need to find the slope using the points (-4,5) and (8,8).

The slope formula is given by:

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

We plug in the values to get:

[tex]m = \frac{8 - 5}{8 - - 4} [/tex]

[tex]m = \frac{3}{12} = \frac{1}{4} [/tex]

Parallel lines have the same slope.

Using the point slope formula, the equation is given by:

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

We substitute the point (-12,-10) to get;

[tex]y - - 10 = \frac{1}{3} (x - - 12)[/tex]

[tex]y + 10 = \frac{1}{4 } (x + 12)[/tex]

Or

[tex]y =\frac{1}{4 } x -7[/tex]
