Question

Refer to the graph. Find the slope of each line

Answer 1

Slope of line 'k' =
`(1)/(2)`

Slope of line 'm' =
`-(1)/(4)`

Explanation:

Slope of a line passing through two points
`(x_1,y_1)` and
`(x_2,y_2)` is given by,

Slope 'm' =
`(y_2-y_1)/(x_2-x_1)`

Sloe of line 'k' which is passing through (-2, 2) and (2, 4) will be,

m =
`(4-2)/(2+2)` =
`(1)/(2)`

Slope of line 'm' having two points (-4, -1) and (0, -2),

m =
`(-1+2)/(-4-0)` = -
`(1)/(4)`
