$\large\boxed{D.\ y=\dfrac{5}{7}x+10}$

Step-by-step explanation:

$Ax+By=C\qquad\text{it's a standard form of an equation of a line}\\\\\\y=mx+b\qquad\text{it's a slope-intercept form of an equation of a line}\\\\\text{We have the equation in the standard form:}\\\\5x-7y=-70\\\\\text{Convert it to the slope - intercept form:}\\\\5x-7y=-70\qquad\text{subtract 5x from both sides}\\\\-7y=-5x-70\qquad\text{divide both sides by (-7)}\\\\y=\dfrac{5}{7}x+10$
