Hi can you please help me with this question I am very confuse.

Use these two point to find the average rate of change, what a tangent line is and what a derivative is/how derivatives relate to tangent lines and slope.

Indicate any intervals where the slope is positive, negative and undefined.

Positive=Dec. 10.2021 - 179.45

Dec. 15.2021 - 179.30

From day one Jan. 25.2021 to Dec 10. 2021 is 319 days

Jan. 25.2021 to Dec 15. 2021 is 324 days

the slope of the linear equation m=(y2- y1) / (x2- x1)

(179.45 - 179.30) / (324 - 319) = 0.03

Negative= May. 5. 2021 - 128.10

May. 12. 2021 - 122.77

From day one Jan. 25.2021 to May. 5. 2021 is 100 days

Jan. 25.2021 to May. 12. 2021 is 107 days

the slope for the linear equation for negative m=(y2- y1) / (x2- x1)

(128.10 - 122.77) / (107 - 100) = 0.76

Undefined = Aug. 6. 2021 - 146.14

Aug. 11. 2021 - 145.86

From day one Jan. 25.2021 to Aug. 6. 2021 is 193 days

Aug. 11. 2021 is 198 days

the slope for the linear equation for undefined m=(y2- y1) / (x2- x1)

(146.14 - 145.86) / (198 - 193) = 0.056
