Bellwork 12/18

Which equation is being represented by this line?

• y = -1x + 2
• y = 1/2x + 2
• y = 3x -4
• y = -3x +2

If I added the line y = -2x + 4 to this graph, what is the solution?

• (2, 0)
• (0, 2)
• (0, 4)
• none of the above

Solve the following system by graphing.  What is the solution? What is -2x+5y?

• 18
• 2
• -2
• 12

Solve for x and y
3x + 2y = 16
7x + y = 19

• (-2,5)
• (-2,-5)
• (2,-5)
• (2,5)
