Answer:
Step-by-step explanation:
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
8). Slope of the line passing through (0, 4) and (-1, 6) will be,
Slope = [tex]\frac{6-4}{-1-0}[/tex]
= -2
9). Slope of a line passing through (10, 15) and (9, 0),
Slope = [tex]\frac{15-0}{10-9}[/tex]
= 15
10). Slope of a line passing through (0, -9) and (4, -7),
Slope = [tex]\frac{-9+7}{0-4}[/tex]
= [tex]\frac{1}{2}[/tex]
11). Slope of a line passing through (2, 20) and (4, 17),
Slope = [tex]\frac{20-17}{2-4}[/tex]
= [tex]-\frac{3}{2}[/tex]
