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

$f(x)=|3x|\\f(2)=|3(2)|\\f(2)=|6|\\f(2)=6$

Problem 2: Solve the equation for y.

$-7x+2y=8$

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

$2y=7x+8$

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

$\frac{2y}{2} =\frac{7x}{2} +\frac{8}{2} \\y=\frac{7}{2}x+4$

Simplify the terms to get the the equation into slope-intercept form.

The slope of the line is $\frac{7}{2}$

I'm a unsure what Problem 3 is asking for sorry I hope the rest is helpful.
