Question

M =Y2-71x2-x1Find the slope of the line that passesthrough these two points,(3, 1) (4,9)m = [?]

Answer 1

`m=8`

1) Since, we've got already two points. Let's plug them into the slope formula so that we can find how steep is the line between those two points:

`m=(y_2-y_1)/(x_2-x_1)=(9-1)/(4-3)=(8)/(1)=8`

2) Thus, that's the slope.
