Answer:
a) rise 5, run 5, slope 1
b) rise 10, run 5, slope 2
Explanation:
The rise is the vertical difference between the points. It is the length of the vertical side of the triangle you have drawn. You can determine that length by counting grid squares or by finding the difference of the y-coordinates of the points.
The run is the horizontal difference between the points. It is the length of the horizontal side of the triangle you have drawn. You can determine that length by counting grid squares or by finding the difference of the x-coordinates of the points.
a)
rise = 5; run = 5. (counting grid squares)
slope = rise/run = 5/5 = 1
__
b)
rise = 10; run = 5. (taking coordinate differences: 5-(-5) = 10; 4-(-1) = 5)
slope = rise/run = 10/5 = 2
