What is the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4) ?
maxonik [38]
ANSWER

y + 5= - \frac{9}{11} (x-3)

or

y - 4= - \frac{9}{11} (x + 8)

EXPLANATION

We want to find the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4).

The point-slope form is given by;

y-y_1=m(x-x_1)

where

m = \frac{4 - - 5}{ - 8 - 3} = \frac{4 + 5}{ - 11} = - \frac{9}{11}

is the slope of the line.

If

(x_1,y_1)=(3,-5)

The point-slope form is

y + 5= - \frac{9}{11} (x-3)

On the other hand, if
(x_1,y_1)=( - 8,4)

Then the point-slope form is,

y - 4= - \frac{9}{11} (x + 8)

These two equations are the same when simplified.
