Consider line \(\ell\)
Line \(\ell\) passes through \(A(-4, -7)\) and \(B(-6, 6)\)
What is the exact gradient of \(\ell\)?
Choose the statement that describes the inclination of line \(\ell\)
Use the signed inverse-tangent result directly
Use the acute reference angle
Use the obtuse supplement of the reference angle
What is the angle of inclination of \(\ell\), to the nearest degree?
