Answer:
C. Write each equation in slope-intercept form.
Step-by-step explanation:
We have been given a system of equations and we are asked to choose the correct option about first step of graphing the system of equation.
Since we know that slope-intercept form of equation is in form [tex]y=mx+b[/tex], where,
m = Slope of the line,
b = Initial value or y-intercept.
When a system of equations is in slope-intercept form, then we can easily graph it as y-intercept will be the point where line will intersect y-axis. The slope of line will show how steep will be the line.
Therefore, option C is the correct choice.
