Answer:

x=3130/3

Step-by-step explanation:

Which is the equation of the given line in point- slope form?

Alina [70]

Answer:

$y-0=-1(x-8)$

Step-by-step explanation:

The given line passes through (0,8) and (8,0).

The slope of this line is $m=\frac{8-0}{0-8} =-1$ .

The point-slope form is given by:

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

We substitute the slope and the point (8,0) to get:

$y-8=-1(x-0)$

We substitute the slope and the point (0,8) to get:

$y-0=-1(x-8)$
