Q:
# Which ordered pairs are on the line with the equation y+3.5=0.75(x-2)? I will mark brainliest. Thanks!

Accepted Solution

A:

Hey! So all you have to do for this question is input the x- and y- values into the equation and simplify:

point 1: (1, 1.75)

y + 3.5 = 0.75 (x - 2)

(1.75) + 3.5 = 0.75 ((1) - 2)

5.25 = 0.75 (-1)

5.25 = -0.75 --> since these are not equation, (1, 1.75) is not correct.

Point 2: (-4, -8)

y + 3.5 = 0.75 (x - 2)

(-8) + 3.5 = 0.75 ((-4) - 2)

-4.5 = 0.75 (-6)

-4.5 = -4.5 --> this is correct because both sides are equal

Point 3: (7, 5.5)

y + 3.5 = 0.75(x - 2)

(5.5) + 3.5 = 0.75((7) - 2)

9 = 0.75(5)

9 = 3.75 --> not equal so not correct

Point 4: (4, -2)

y + 3.5 = 0.75(x - 2)

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

1.5 = 0.75( 2)

1.5 = 1.5 --> equal so correct

So (-4, -8) and (4, -2) are your answers! Hope this helped :)
