Finding Slope Given Two Points
x 3 4 5 y 5 7 9 Find the slope of the line from the above table
What is a slope of 2
Define Slope
What is a constant rate of change or what is rise over run
The relation {(1, 2), (2, 4), (3, 6), (1, 5)}
No, the input 1 has two outputs
What is the formula for slope with two points
What is y2-y1/x2-x1
A table where each x-value is paired with exactly one y-value
Yes!
What is the vertical change between two points
The rise
Input: Teacher
Output: Classes taught
Not a function, teacher can teach multiple classes
Find the slope of the line containing the following points (-2,5) (4,-7)
What is -1/2
x 1 2 3 y 4 -2 -8
What is a slope of -6
This word describes the horizontal change between two points on a line.
The run
{(−1, 3), (0, 3), (1, 3), (2, 3)}
Function (different inputs can share the same output)
Find the slope of the line containing the following points (-3,-7) (5,2)
What is 9/8
{(1, 4), (2, 8), (3, 4), (4, 8)}
→ Function (outputs can repeat; inputs cannot)
