Answer:
C. Solve for the variable y.
Explanation:
You want to know what needs to be done to an equation to find the slope and y-intercept.
Slope-intercept form
The slope-intercept form of the equation for a line is ...
y = mx + b
This is a polynomial equation written in standard form with the terms in decreasing order of the power of the variable. In this equation, the coefficient 'm' is the slope of the line, and the constant 'b' is the y-intercept on the graph.
This equation can be obtained from other forms of the equation for a line by solving for y and arranging the terms to match this form. That is, to find the slope and y-intercept, what needs to be done is ...
C. Solve for the variable y.

Additional comment
The description "standard form" as used above applies to polynomials in general. Specific polynomial equations, as for lines, circles, ellipses, hyperbolas, have their own "standard form."
The form called "standard form" for a linear equation is ...
ax +by = c
where a, b, c are mutually prime integers with a > 0. In the case of a horizontal line, b > 0.
