What is the slope of the line graphed?

• 1

• -1

• 2

• -2

The y-intercept of the line is

Graph the equation y=2x+1 in the same coordinate plane to represent a system. At which point(s) do the lines intersect?

How many ordered pairs are solutions of the system? Explain your thinking.

Select all equations that would also have infinitely many solutions when graphed in the same plane as the line y-1=2x.

• 2y-2=4x

• 3y-1=6x

• 3y=6x+3

• 2y=4x-2
