Answer:
- 3 , 3 , 0
Step-by-step explanation:
calculate the gradient (slope) m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, 11 ) and (x₂, y₂ ) = (6, 2 )
m = [tex]\frac{2-11}{6-3}[/tex] = [tex]\frac{-9}{3}[/tex] = - 3
---------------------------------------------
with (x₁, y₁ ) = (1, - 2 ) and (x₂, y₂ ) = (4, 7 )
m = [tex]\frac{7-(-2)}{4-1}[/tex] = [tex]\frac{7+2}{3}[/tex] = [tex]\frac{9}{3}[/tex] = 3
--------------------------------------------
with (x₁, y₁ ) = (2, 14 ) and (x₂, y₂ ) = (5, 14 )
m = [tex]\frac{14-14}{5-2}[/tex] = [tex]\frac{0}{3}[/tex] = 0
