Answer:

Not correct.

Step-by-step explanation:

If we plug in the x values into the equation we don't get anyway near to the y-values:

x = 2, y = 2.5(2) + 1.5 = 6.5 - comp[are this with y = -4 of the point(2, -4).

when x = 4, y = 11.5 ( compared with -7) and

when x = 5, y = 14 (compared with  -12).
