Answer:

B.The slopes of both lines are different but the y-intercepts are the same.

Explanation:

The slope-intercept form of the equation of a line is:

[tex]y=mx+b[/tex]

First, make the subject of equations A and B y.

Equation A:

[tex]\begin{gathered} 4x-2y=-6 \\ 2y=4x+6 \\ y=\frac{4x}{2}+\frac{6}{2} \\ y=2x+3 \end{gathered}[/tex]

Equation B:

[tex]\begin{gathered} 3x+y=3 \\ y=-3x+3 \end{gathered}[/tex]

Thus:

• The slope of Equation A is 2 while the y-intercept is 3.

,

• The slope of Equation B is -3 while the y-intercept is 3.

The slopes of both lines are different but the y-intercepts are the same.

The correct choice is B.
