Answer:
2) a. slope = 4/3
2) b. slope = -4
Step-by-step explanation:
The slope of the line that passes through points
[tex] (x_1, y_1) [/tex] and [tex] (x_2, y_2) [/tex]
is m, given by the slope formula below:
[tex] m = \dfrac{y_1 - y_2}{x_2 - x_1} [/tex]
2) a. (30, 32) and (18, 16)
[tex] m = \dfrac{y_1 - y_2}{x_2 - x_1} [/tex]
[tex] m = \dfrac{32 - 16}{30 - 18} [/tex]
[tex] m = \dfrac{16}{12} [/tex]
[tex] m = \dfrac{4}{3} [/tex]
2) b. (4, -26) and (10, -50)
[tex] m = \dfrac{y_1 - y_2}{x_2 - x_1} [/tex]
[tex] m = \dfrac{-50 - (-26)}{10 - 4} [/tex]
[tex] m = \dfrac{-24}{6} [/tex]
[tex] m = -4 [/tex]
