Find the missing angle measures: I 42 X Х B А 9 А 10 B 11 C 12 S 13 T 14 X 40 48 57 41 76 SIT 46 15 Lines that are parallel have slopes that are: 16 Write the slope formula: 17 Calculate the slope of a line going through: (12,5) and (22,13):

Respuesta :

15.

Lines that are parallel has slope that are equal

16.

The slope formula is;

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

where m is the slope

17. points given are;

(12, 5) and (22, 13)

x₁=12 y₁=5 x₂=22 y₂=13

substituting the values into the formula;

[tex]m=\frac{13-5}{22-12}[/tex]

[tex]m=\frac{8}{10}=\frac{4}{5}[/tex]

slope of the line is 4/5
