Question

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

Answer 1

1

Explanation:

Answer 2

19:

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

20:

`slope = (y _(2) - y _(1))/(x _(2) - x _(1) ) \\ \\ slope = (19 - 13)/( - 1 - 0) = (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 = (y _(2) - y _(1))/(x _(2) - x _(1) ) \\ \\ slope = (15 - 3)/(8 - 2) = (12)/(6) \\ \\ { \underline{ \: \: slope = 2 \: \: }}`
