Which is a reasonable first step to solve the system? $$-5x+6y=12$$ $$y=\frac{5}{6}x+2$$

Substitute the expression $$\frac{5}{6}x+2$$ in place of y in the first equation.

Substitute $$\frac{5}{6}x-2$$ in place of y in the first equation.

Substitute the expression $$-5x+12$$ in place of y in the second equation.

Substitute the expression $$6y+12$$ in place of y in the second equation.

Marco is observing the system of equations below and believes it will have exactly one solution. Is he correct? Why or why not?

No, the slopes are the same and the y-intercepts are different, so there would be no solution to the system of equations.

No, the slopes are the same and the y-intercepts are different, so there would be infinite solutions to the system of equations.

Yes, the slopes are the same so they will intersect and have one solution.

Yes, the y-intercepts are different so they will intersect and have one solution.

Which of the following is true about the solution to the system of equations below? $$x+2y=-2$$ $$-3x-y=21$$

The x-value of the solution is -8.

The y-value of the solution is 3.

The lines will have the same slope and same y-intercepts.

The lines will have the same slope but different y-intercepts.

The lines will have different slopes and different y-intercepts.

The lines will have different slopes but the same y-intercepts.
