Verified answer

..........y2 - y1

m = ---------------

.........x2 - x1

.........- 7 - 3

m = ---------------

..........4 - (-1)

m = - 2 answer//

D. -2

Solution:

Slope(m)=(-7-3)/(4+1)

m=-10/5

m=-2

The answer is -2. You can find the answer by putting the points into this formula:

y2 - y1 / x2 - x1

So in the points (-1, 3) and (4, -7)

y2 is -7 and y1 is 3

x2 is 4 and x1 is -1

Therefore: -7 - 3 / 4 - (-1)

Which is -10 / 5 or -2

(-1, 3) and (4, –7)

Find the slope

(y1-y2)/(x1-x2)

(3+7)/ (-1-4)= 10/-5= -2 so D

m = (-7 - 3) / (4 + 1)

m = - 10 / 5 = - 2

OPTION D

What's the difference between the y coordinates (ie how much does it go up)? 3 - (-7) = 10

What's the difference between the x coordinates (ie how much does it go along)? -1 - 4 = -5

How many units does it go up for each unit it goes along?

10/(-5) = -2

ie slope = -2 (D)
