Answer:

The points are not on the same line

Step-by-step explanation:

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the coordinates of the given points:

for A(3, 5) and B(-2, 6):

[tex]m_{AB}=\dfrac{6-5}{-2-3}=\dfrac{1}{-5}=-\dfrac{1}{5}[/tex]

for B(-2, 6) and C(-5, 7):

[tex]m_{BC}=\dfrac{7-6}{-5-(-2)}=\dfrac{1}{-5+2}=\dfrac{1}{-3}=-\dfrac{1}{3}[/tex]

[tex]\large\boxed{m_{AB}\neq m_{BC}}[/tex]
