You can see that this line passe through the points (-4,-2) and (4,3).

The slope of the line passing through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is

[tex]\dfrac{y_2-y_1}{x_2-x_1}.[/tex]

Thus, the slope is

[tex]\dfrac{3-(-2)}{4-(-4)}=\dfrac{5}{8}.[/tex]

Then the equation of the line is

[tex]y-3=\dfrac{5}{8}(x-4),\\\\y=\dfrac{5}{8}x+\dfrac{1}{2}.[/tex]

Answer: correct choice is C.
