What is the slope of a line that passes through points (-1, 4) and (4, 9)?
Ok here is the graph. And all of the Different slopes.
The slope would be Positive Slope!
The slope is (difference in 'y') divided by (difference in 'x') .
Difference in 'y' = (9 - 4) = 5
Difference in 'x' = (4 - [-1]) = 5
Slope = 5/5 = 1 .
(I don't think we need the pictures at all.)
