Question

which points would be on the line $y = 2.5x$, select two answers. a (10,4) b (5,2) c (2,5) d (4,10)

Explanation:

Step1: Check point A (10,4)

Substitute \( x = 10 \) into \( y = 2.5x \), we get \( y = 2.5\times10 = 25
eq 4 \). So A is not on the line.

Step2: Check point B (5,2)

Substitute \( x = 5 \) into \( y = 2.5x \), we get \( y = 2.5\times5 = 12.5
eq 2 \). So B is not on the line.

Step3: Check point C (2,5)

Substitute \( x = 2 \) into \( y = 2.5x \), we get \( y = 2.5\times2 = 5 \). So C is on the line.

Step4: Check point D (4,10)

Substitute \( x = 4 \) into \( y = 2.5x \), we get \( y = 2.5\times4 = 10 \). So D is on the line.

Answer:

C. (2,5), D. (4,10)
