The equation of the line is y = -x + 9.

Step-by-step explanation:

First, you have to find the gradient by choosing any 2 coordinates that lies on the line. I will choose (0,9) and (9,0). Then you have to substitute it the the formula.

Next, you have to put into the slope-form equation, y = mx + c where m represents gradient which is -1 and c is y-intercept. In order to find c in a faster way, you can look at the graph to see which coordinates touches y-axis. So the value of c is 9 :

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:

have a nice day!
