We have to find the slope first:
[tex]m=\frac{1.9-2.14}{5\text{ - 3}}=\text{ }\frac{-0.24}{2}=\text{ -0.12}[/tex]
With m, and any x and y value we find b
[tex]\begin{gathered} 3=(\text{ -}0.12)(2.14)+b \\ 3=\text{ -}0.2568\text{ + b} \\ b=3.2568\text{ = 3.}3 \end{gathered}[/tex]
The equation is:
y = -0,12x + 3.3
