Problem 1: Plug in the given value into the function and evaluate.

Problem 2: Solve the equation for y.

add 7x to both sides to move it to the right side of the equation.

Divide both sides of the equation by 2 to get a single y variable on the left hand side.

Simplify the terms to get the the equation into slope-intercept form.
The slope of the line is 
I'm a unsure what Problem 3 is asking for sorry I hope the rest is helpful.
B is equal to 51 because angles in a right angle add up to 90
Answer:
-171
Step-by-step explanation:
Applying PEMDAS (order of operations),
We open the parenthesis first;
-9 - (
)³ × 6
-9 - 3³ × 6
We work on multiplication next;
-9 - 27 × 6 = -9 - 162
finally we do subtraction to get;
-9 - 162 = -171
