I'm thinking line 2 and 3 are Parallel
Answer:
y = -(1/7)x + 1
Step-by-step explanation:

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)
X=3
10- 4x=7x-23
14x-7x=123-10
-11x=-23-10
11x=-33÷(-11)
x=3
