Answer! :

y = -2x + 5

Step by Step! :

slope intercept form:

y = mx + b

m being slope, b being the y intercept.

To find the slope, use this equation:

y^2 - y^1 / x^2 - x^1

Plug in your points.

(-1) - (7) / (3) - (-1)

-8 / 4

-2 is your slope! (y = -2x + b)

To solve for b, plug in any one of your points and solve for b. Let's use (3, -1)

-1 = -2(3) + b

-1 = -6 + b

5 = b

Your new equation is...

y = -2x + 5

What is the slope of line segment AB?<br> A) 2/3<br> B) 3/4<br> C) 4/3<br> D) -3/4
Lunna [17]

For this case we have that by definition, the slope of a line is given by:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

Where:

(x_ {1}, y_ {1})and (x_ {2}, y_ {2})are two points through which the line passes.

According to the image we have:

(x_ {1}, y_ {1}): (-5,3)\\(x_ {2}, y_ {2}): (3, -3)

Substituting we have:

m = \frac {-3-3} {3 - (- 5)} = \frac {-6} {3 + 5} = \frac {-6} {8} = - \frac {3} {4}

Thus, the slope of the line is:

m = - \frac {3} {4}

Answer:

m = - \frac {3} {4}
