How do you find the slope of

(- 9, - 3), (- 7, - 5)

https://socratic.org/questions/how-do-you-find-the-slope-of-9-3-7-5

slope = - 1

Explanation: To calculate the slope use the

gradient formula

(\overline{\underline{∣ ∣ ∣ ∣ ∣ (\frac{2}{2}) (m = \frac{y _{2} - y _{1}}{x _{2} - x _{1}}) (\frac{2}{2}) ∣ ∣ ∣ ∣ ∣}})

How do you combine

(- 9 + i) + (6 - 2 i)

https://socratic.org/questions/how-do-you-combine-9-i-6-2i

- 3 - i

Explanation: You may add real and complex parts separately for a complex number in rectangular form.

∴ (- 9 + i) + (6 - 2 i) = (- 9 + 6) + i (1 - 2)
