x 31 36 41 46
y 10 8 6 4
I need to find the slope with these points
we know that
To find out the slope, we need two points
take the points (31,10) and (36,8)
so
m=(8-10)/(36-31)
m=-2/5
m=-2/5
m=-0.40
therefore
the answer is -0.40
Part 2)
we have
x -7 -4 -1 2
y -7 14 35 56
take the points (7,-7) and (-4,14)
m=(14+7)/(-4-7)
m=21/-11
m=-21/11
the answer is -21/11
