Question

What is the slope of the line that passes through the pair of points? (1, 7), (10, 1) A. 3/2 B. -3/2 C. -2/3 D. 2/3

Answer 1

\[m = (y _{2}-y _{1})/(x _{2}-x_{1})\]

Answer 2

it can be solved by using the slope formula as suggested by ASNinja.
slope(m) = (y2 - y1) / (x2 - x1)
(1,7) x1 = 1 and y1 = 7
(10,1) x2 = 10 and y2 = 1
now just sub
slope(m) = (1 - 7) / (10 - 1) --- can you finish ??

Answer 3

y-y1/x-x1 = y2-y1/x2-x1
y-7/x-1 = 1-7/10-1
y-7/x-1 = -6/9
y-7 = -6x/9 +6/9
y=-6x/9 + 23/3

i think im doing that right if not let me know please

Answer 4

what are you doing ??
slope(m) = (y2 - y1) / (x2 - x1)
and when we subbed our points in, we got :
slope(m) = (1 - 7) / (10 - 1)
slope(m) = -6/9 which reduces to - 2/3

Answer 5

oh right i see what u did.. sorry I get confused with math
