Find the slope of the line that passes through the given points (2,-,6) (3,,6) (-4,,7)

The slope is

−

1

.

Here's how I did it:

explanation:

To find the slope of something, we do

△

y

△

x

, or change in y over change in x, or

y

2

−

y

1

x

2

−

x

1

.

In your question, you have two points on the line,

(

−

2

,

5

)

and

(

6

,

−

3

)

. So we can plug them into the equation above and solve for the slope.

(below, m means slope)

m

=

−

3

−

5

(

2

)

m

m

The slope is

−

1

.
