Question

What is the slope of the line that passes through (3, -2) and (-1, -1)?

1/4

-1/4

-4/1

4/1

Answer 1

ok....we are given 2 sets of points

set 1 is (3,-2)....so we will call x1 = 3 and y1 = -2
set 2 is (-1,-1)...x2 = -1 and y2 = -1

now we use the slope formula:
slope = (y2 - y1) / (x2 - x1)
now we sub out info into the formula
slope = (-1- (-2) / (-1 - 3) -- pay close attention to your signs
slope = (-1 + 2) / -4
slope = 1/-4 or -1/4
