The equation y = x + a is graphed in the xy-plane, where a is a positive constant. A second equation, y = x -- a, is graphed in the same xy-plane. How do the slope and y-intercept of the
graph of the first equation compare with the slope and y-intercept of the graph of the second
equation?

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:
