Solve for the values of y given the values of x a) y = 1/3x -2. when x = -12 and x = 0 b) y = -x -4. when x = -4 and x = 4

a) To find the values of y, we substitute the given x values into the equation y = 1/3x - 2.

When x = -12: y = 1/3*(-12) - 2 y = -4 - 2 y = -6

When x = 0: y = 1/3*0 - 2 y = 0 - 2 y = -2

b) Similarly, we substitute the given x values into the equation y = -x - 4.

When x = -4: y = -(-4) - 4 y = 4 - 4 y = 0

When x = 4: y = -(4) - 4 y = -4 - 4 y = -8

So, the values of y for the given x values are:

a) y = -6 when x = -12 and y = -2 when x = 0 b) y = 0 when x = -4 and y = -8 when x = 4
