(6-2)/(9-7) = 4/2 = 2 yes d
(-9+4)/(6-3) = -5/3 so I think b
2. What is the slope of the line that passes through the pair of points? (7,2) and (9,6)
a. -1
b. -2
c. 1
d. 2
I think it's d
3. What is the slope of the line that passes through the pair of points? (3,-4) and (6,-9)
a. 5/3
b. -5/3
c. 3/5
d. -3/5
i think it's a
I'm not 100% sure about either of these.

m = slope
m = ( y2 - y1 ) / ( x2 - x1 )
2.
x1 = 7
y1 = 2
x2 = 9
y2 = 6
m = ( y2 - y1 ) / ( x2 - x1 ) = ( 6 - 2 ) / ( 9 - 7 ) = 4 / 2 = 2
Answer d
3.
x1 = 3
y1 = - 4
x2 = 6
y2 = - 9
m = ( y2 - y1 ) / ( x2 - x1 ) = [ - 9 - ( - 4 ) ] / ( 6 - 3 ) = ( - 9 + 4 ) / 3 = - 5 / 3
Answer b
m = ( y2 - y1 ) / ( x2 - x1 )
