How do you think we could find what the slope of Mt. Everest is?
Which Mountain has the steepest slope?
Mt. Makalu Mt.Annapurna Mt. EverestVertical Height= 27,766ft VH 26,545ft VH= 29,035ftHorizontal Distance= 7,828ft HD=9,790ft HD = 4,924ft
Slope
The steepness of a line is called the Slope of the line. Slope compares the Vertical change (the rise) to the horizontal change (the run), when we go from 1 point to another.

Find the Slope using 2 points
Given: (-3, 4), (2, -2)
Possibilities for a Line's Slope
Positive Slope Zero Slope Negative Slope Undefined Slope
Point-Slope Form The Point-Slope Form is an equation of a line that is
found using the slope and 1 point from the line.

y− y1=m( x−x1)
Given the Slope and a point give the Point-Slope Form
Given m=2; (1,5) Given m=4; (-1,3)
y− y1=m( x−x1)
Given 2 points give the Point-Slope Form and solve for y
