Answer:

y= $\frac{-3}{5}x -2$

Step-by-step explanation:

find the gradient by rearranging the equation, y= $\frac{-3}{5}x$ + $\frac{18}{5}$

from here we can see that the slope or gradient is $\frac{-3}{5}x$

now using the equation y-y2 = f'(x1)(x-1) we find the equation by subbing

= y- (-4) = $\frac{-3}{5}$ (x - [-10])

= y + 4 = $\frac{-3}{5}x -6$

= y= $\frac{-3}{5}x -2$
