Answer:
[tex]y=\frac{4}{7} x-\frac{9}{7}[/tex]
Step-by-step explanation:
The yellow points are on (4,1) and (8,8).
The slope is [tex]\frac{8-4}{8-1} =\frac{4}{7}[/tex]
In point-slope form the equation is y-1=[tex]\frac{4}{7}[/tex](x-4)
Expand and add 1 to get y=[tex]\frac{4}{7}[/tex]x-[tex]\frac{9}{7}[/tex]
