Given the equation:
y= -200 - 6x
Determine the value of y, when x = -12
Solution:
Substitute the value of x which is -12 in the given equation of y.
y = -200 -6(-12)
y = -200 + 72
Noticed that the sign changes to positive, since a common rule states that in multiplying or dividing numbers with the same sign, the answer will be positive, if the signs are opposite, then the answer is negative.
y = -128
The value of y is -128.
