Question

If (6,39) and (-5,-49) are two anchor pint find the equation of the line

Answer 1

Answer:

$y =8x+9$

Step-by-step explanation:

The points are (6,39) and (-5,-49)

We need to find the equation of this line.

The slope is given by:

$m = \frac{y_2-y_1}{x_2-x_1}$

$m = \frac{ - 49 - 39}{ - 5 - 6}$

$m = \frac{ - 88}{ - 11}$

$m = 8$

We use the formula:

$y-y_1=m(x-x_1)$

We substitute the point (6,39) and m=8 to get:

$y - 39 = 8(x - 6)$

We expand to obtain:

$y - 39=8x-48$

$y =8x-48 + 39$

$y =8x + 9$
