Answer:
a) [tex] \frac{4}{3} [/tex]
b) -1
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
where (x₁, y₁) is the first point and (x₂, y₂) is the second point
6a) Slope
[tex] = \frac{7 - 3}{4 - 1} [/tex]
[tex] = \frac{4}{ 3} [/tex]
6b) Slope
[tex] = \frac{6 - 5}{2 - 3} [/tex]
[tex] = \frac{1}{ - 1} [/tex]
= -1
