Answer:


y-5=(4)/(3) (x-6)

Explanation:

Pre-Solving

We are given that a line that passes through (6, 5) and (-3, -7). We want to write the equation in point-slope form.

Point-slope form is given as
y-y_1=m(x-x_1) where m is the slope and
(x_1,y_1) is a point.

First, we need to find the slope of the line.

Solving

Slope

The slope (m) can be found using the equation
(y_2-y_1)/(x_2-x_1) where
(x_1,y_1) and
(x_2,y_2) are points.

We can label the values of the points:


x_1=6\\y_1=5\\x_2=-3\\y_2=-7

Now, substitute into the equation.


m=(y_2-y_1)/(x_2-x_1)


m=(-7-5)/(-3-6)


m=(-12)/(-9)


m=(4)/(3)

The slope of the line is
(4)/(3).

Equation

Substitute m as
(4)/(3) in
y-y_1=m(x-x_1).


y-y_1=(4)/(3) (x-x_1)

Now, substitute 6 as
x_1 and 5 as
y_1.


y-5=(4)/(3) (x-6)

Answer:

The point-slope equation is
y-5=(4)/(3) (x-6)

The point-slope form of the equation for a line is given by
y-y_1=m(x-x_1), where
(x_1,y_1) is a point on the line and m is the slope.

1. Find the slope


m=(y_2-y_1)/(x_2-x_1)


=((-7)-5)/((-3)-6)


=(-12)/(-9)


=(4)/(3)

2. Choose a point on the line, let's say (6,5) and substitute


y-5=(4)/(3)(x-6)
