Answer:
y= [tex]\frac{-3}{5}x -2[/tex]
Step-by-step explanation:
find the gradient by rearranging the equation, y= [tex]\frac{-3}{5}x[/tex] +[tex]\frac{18}{5}[/tex]
from here we can see that the slope or gradient is [tex]\frac{-3}{5}x[/tex]
now using the equation y-y2 = f'(x1)(x-1) we find the equation by subbing
= y- (-4) = [tex]\frac{-3}{5}[/tex] (x - [-10])
= y + 4 = [tex]\frac{-3}{5}x -6[/tex]
= y= [tex]\frac{-3}{5}x -2[/tex]
