Question

Given the line passing through (-7,5) and (-4,18), what is the correct slope of the line?

Answer 1

Answer:
`(13)/(3)`

Explanation:

Slope of a line can be determined by dividing the differences between Y coordinates and X coordinates of two given points. i.e,

Slope of a line =
`(y_(2)-y_(1) )/(x_(2)-x_(1)  )`

Given,

`x_(1) = -7` and
`y_(1) = 5`

`x_(2) = -4` and
`y_(2) = 18`

Now, by substituting the values in above formula, we get:

Slope of a line =
`(18-5)/(-4-(-7))`

=
`(13)/(3)`
