Question

Find the slope for each line based on the given representation​

Answer 1

Answer:

19:

$slope = \frac{y _{2} - y _{1}}{x _{2} - x _{1} } \\ \\ slope = \frac{0 - ( - 5)}{5 - 0} = \frac{5}{5} \\ \\ { \underline{ \: \: slope = 1 \: \: }}$

20:

$slope = \frac{y _{2} - y _{1}}{x _{2} - x _{1} } \\ \\ slope = \frac{19 - 13}{ - 1 - 0} = \frac{6}{ - 1} \\ \\ { \underline{ \: \: slope = - 6 \: \: }}$

21:

• Considering general equation of a line:

$y = mx + b$

m is the slope, therefore

slope = -3/5

22:

$slope = \frac{y _{2} - y _{1}}{x _{2} - x _{1} } \\ \\ slope = \frac{15 - 3}{8 - 2} = \frac{12}{6} \\ \\ { \underline{ \: \: slope = 2 \: \: }}$
