Question

Find the slope between the points:(1,7)(-2,3)

Answer 1

slope =
`(4)/(3)`

Explanation:

calculate the slope m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (1, 7 ) and (x₂, y₂ ) = (- 2, 3 )

m =
`(3-7)/(-2-1)` =
`(-4)/(-3)` =
`(4)/(3)`

Answer 2

Using the formula,

`m=(7-3)/(1-(-2))\rightarrow m=(4)/(1+2)\rightarrow m=(4)/(3)`
