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.

Option A:
Step-by-step explanation:
Given polynomials are (5x + 8 – 6x) and (4 + 2x –7).
Let us first simplify the expression:
Combine like terms.
(5x + 8 – 6x) = (5x – 6x + 8) = –x + 8
(4 + 2x –7) = (4 – 7 + 2x) = –3 + 2x
Product of (5x + 8 – 6x) and (4 + 2x –7)
= (5x + 8 – 6x)(4 + 2x –7)
= (–x + 8)(–3 + 2x)
Multiply each term of one expression with each term of the other expression.
= (–x)(–3) + (–x)(2x) + 8(–3) + 8(2x)
Combine like terms and add.
Arranging the equation, starting with highest power.
Hence, the product of the two given polynomials is
