in respect to y 2y*3-y collecting the three times the coefficient of y which is 2 6y-y 6y-y=5y the derivative of 5y in respect to y is 5.
Multiply the coefficient by all the values inside the brackets.Example 1:2(y+1)= 2 X y + 2 X 1= 2y + 2Example 2:3 X 5y(y+4)= 3 X (5y X y) + (5y X 4)= 3 X 5y2 + 20y
5y - 2 = 28 - y 5y + y = 28 + 2 6y = 30 y = 30/6 y = 5
y = 5y = 5y = 5y = 5
-5y-35 = -4x -5y = -4x+35 y = 4/5x-7 The y intercept is -7
