We choose the points:
(1, 1859) and (8, 4372)
The equation is of the form y = mx + b, where
slope:
[tex]m=\frac{y2-y1}{x2-x1}=\frac{4372-1859}{8-1}=\frac{2513}{7}=359[/tex]intercept:
[tex]\begin{gathered} y=mx+b \\ 1859=359(1)+b \\ 1859-359=359+b-359 \\ b=1500 \end{gathered}[/tex]So, the equation is:
[tex]y=359x+1500[/tex]
