Good afternoon!
Head to GOFO!
Brain Dump:
Tell me everything you know/remember about SLOPE.
Positive, neg, zero, undefined, increase decrese, steepness

2. Can Use Calc. on computer
Positive, neg, zero, undefined, increase decrese, steepness

3. * IXL slope formula today
AGENDA
*Test Analysis
*Slope Formula
* IXL slope formula today
*F-IF.6 Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph. ★
(i) Tasks have a real-world context.
Positive, neg, zero, undefined, increase decrese, steepness

7. *Can be +, -, undefined or zero slope
Slope what do you know?
*Determine from graph
*Rise over Run
*Can be +, -, undefined or zero slope
*It is the measure of steepness of a line

11. Slope what do you know?
𝑾𝒉𝒂𝒕 𝒅𝒊𝒅 𝒘𝒆
do with the
coordinates?

12. The difference of the y and the difference of the x
Slope Formula Song
The difference of the y and the difference of the x
Also known as rise over run
Divide the two
And then reduce
And you’ve got slope, slope, slope, slope, slope, slope, slope, slope

14. Slope Formula

15. When might it be
easier to use the slope formula rather than graphing and counting rise over run?
