Hello!
The slope intercept equation for a line is y=mx+b, where b is the y-intercept, and m is the slope. As you can see, the slope is always multiplied by x.
As you can see, -5/4 is multiplied by x. Therefore, our slope is -5/4.
I hope this helps!
Basically a terminating decimal is a decimal with an exact answer when you have no remainder left over. A repeating decimal is when you can never reach zero no matter how many times you divide the answer. It is always written with a line on top to show that it goes on forever and ever and it never ends.
The answer is the option d, which is: d) 
The explanation for this problem is shown below:
1. Smplify the denominator and rewrite the numerator in this form:
2. Multiply the denominator and the numerator by the conjugated 
and simplify the expression, as following:
3. As you can see, you obtain the expression shown in the option mentioned above.
2/3b = 12
First you have to get rid of 2/3, so you multiply both sides by its reciprical:
(3/2) 2/3b = 12 (3/2) -->b = 36/2 --> b = 18
