Question

Ind the slope, if it exists, of the (-16,-4) and (-20,-7)

Answer 1

slope =
`(3)/(4)`

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 16, - 4 ) and (x₂, y₂ ) = (- 20, - 7 )

substitute these values into the formula for m

m =
`(-7-(-4))/(-20-(-16))` =
`(-7+4)/(-20+16)` =
`(-3)/(-4)` =
`(3)/(4)`
