Answer:
slope: [tex]\bold{m=3}[/tex]
equation: [tex]\bold{y-2=3(x-1)}[/tex]
Step-by-step explanation:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\(1,\,2)\ \implies\ x_1=1\,,\ y_1=2\\(0,\,-1)\ \implies\ x_2=0\,,\ y_2=-1\\\\m=\dfrac{-1-2}{0-1}=\dfrac{-3}{-1}=3[/tex]
[tex]y-y_1=m(x-x_1)[/tex] - point-slope form of Equation of the Line
[tex]x_1=1\,,\ y_1=2\,,\ m=3\\\\equation:\\{}\qquad\qquad y-2=3(x-1)[/tex]
