First: info on point-slope form.
We need to find the slope of the line first.
[tex]m = \frac{2 + 1}{5 - 1} = \frac{3}{4}[/tex]
Slope: [tex]\frac{3}{4}[/tex]
Now we can complete the point-slope equation of the line.
[tex]y - (-1) = \frac{3}{4}(x - 1)\\\\y + 1 = \frac{3}{4}(x - 1)[/tex]
*These equations are equivalent.
