Question

4. Four systems of equations are shown in the table. Indicate whether each system has no solution, one

Answer 1

Answer:

Bbhhggggggg is the only one of those who have a great relationship with their

Answer 2

Answer:

• y = 3x + 1
• y = 3x + 5

No solution, parallel lines as same slope of 3

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

One solution

• 3x + 2y = 2  ⇒ y= -1.5x+1
• 3x + 2y = 5  ⇒ y= -1.5x+5

No solution, parallel lines as same slope of -1.5

• x - 2y = 1
• 2x - 4y = 2 ⇒ x- 2y= 1

Infinitely many solutions as 2 overlapping lines
