Which ordered pairs are on the line with equation y-0.75=1.25 (x-3) ?

Select each correct answer. (Multiple choice question.)

(4,2)

(1,1.75)

(7,5.5)

(-4,-8)

Replace x and y of the equation with the x - and y-coordinates, respectively, of each pair in the choices. If the equation becomes a true statement, then that ordered pair is on the line.

A. (4, 2)

y - 0.75 = 1.25 (x - 3)

2 - 0.75 = 1.25 (4 - 3)

1.25 = 1.25 (1)

1.25 = 1.25

Since 1.25 = 1.25 is a true statement, the ordered pair (4, 2) is on the line.

B. (1, 1.75)

y - 0.75 = 1.25 (x - 3)

1.75 - 0.75 = 1.25 (1 - 3)

1 = 1.25 (-2)

1 = - 2.5

Since 1 = - 2.5 is a false statement, the ordered pair (1, 1.75) is not on the line.

Now try the same process for options C and D.
