Question

Which statement best describes the first step of solving the given system of equations by graphing?

3x-y=4
x+y=-4

A. Identify the point of intersection.
B. Graph each line.
C. Write each equation in slope-intercept form.
D. Write the solution as an ordered pair.

Answer 1

The answer is C-write each equation in slope-intercept form.

Answer 2

C. Write each equation in slope-intercept form.

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
`y=mx+b`, 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.
