Drag and drop the correct coordinates to show that

(2, 0) is the solution to the system:

y = 1/2x – 1 and y = –3x + 6

(​ (a)   ) = 1/2(​ (b)   ) – 1

(​ (c)   ) = –3(​ (d)   ) + 6

• 0
• 2
• 1
• 6
• -3

Drag and drop the correct coordinates to show that

(1, 2) is the solution to the system:

y = 5x – 3 and y = –4x + 6

(​ ​ (a)   ) = 5(​ ​ (b)   ) – 3

(​ (c)   ) = –4(​ ​ (d)   ) + 6

• 2
• 1
• 6
