Given y + 3.5 = 0.75 (x - 2)

when x = 4,

y + 3.5 = 0.75 (4 - 2) = 0.75 (2) = 1.5

y = 1.5 - 3.5 = - 2.

Thus, the ordered pair (4, - 2) is the line with equation y + 3.5 = 0.75 (x - 2)

When x = - 4,

y + 3.5 = 0.75 (-4 - 2) = 0.75 (-6) = - 4.5

y = - 4.5 - 3.5 = - 8

Thus, the ordered pair (-4, - 8) is the line with equation y + 3.5 = 0.75 (x - 2)

When x = 1,

y + 3.5 = 0.75 (1 - 2) = 0.75 (-1) = - 0.75

y = - 0.75 - 3.5 = - 4.25

Thus, the ordered pair (1, 1.75) is not on the line with equation y + 3.5 = 0.75 (x - 2)

When x = 7,

y + 3.5 = 0.75 (7 - 2) = 0.75 (5) = 3.75

y = 3.75 - 3.5 = 0.25

Thus, the ordered pair (7, 0.25) is not on the line with equation y + 3.5 = 0.75 (x - 2)
