Hi there!
• ( x₁ , y₁ ) = ( -12 , 15 )
• ( x₂ , y₂ ) = ( 0 , 4 )
by Slope formula :-
m = [tex]\dfrac {y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
=> m = [tex]\dfrac {4 - 15}{0 - (-12)}[/tex]
=> m = [tex]\dfrac {-11}{0 + 12}[/tex]
=> m = [tex]\dfrac {-11}{12}[/tex]
Hence,
The slope of th' line is [tex]\dfrac {-11}{12}[/tex]
~ Hope it helps!
