Answer:

y - 3 = [tex]-\frac{1}{2}[/tex](x - 1)

Step-by-step explanation:

slope m = (y₂ - y₁) / (x₂ - x₁)

             = (4 - 3) / (-1 - 1)

             = [tex]-\frac{1}{2}[/tex]

Point slope form:

y - y₁ = m(x - x₁)

y - 3 = [tex]-\frac{1}{2}[/tex](x - 1)

can be further simplify:

y - 3 = [tex]-\frac{1}{2}x[/tex] + [tex]\frac{1}{2}[/tex]

y - 7/2 = -1/2x
