Answer:
-2/35
Step-by-step explanation:
Slope y-intercept form : y = mx + b
Here m is the slope and b is the y-intercept
Write the given equation in slope y-intercept form.
[tex]\sf \dfrac{2}{7}x + 5y = 15\\\\[/tex]
[tex]\sf 5y = \dfrac{-2}{7}x + 15\\\\ y =\dfrac{-2}{7*5}x + \dfrac{15}{5}\\\\ y = \dfrac{-2}{35}x + 3\\\\ \boxed{\bf Slope = \dfrac{-2}{35}}[/tex]
