4. Using the graph below, what is the solution to -2x + 4 = -2? How can you tell?
4Y
2 4
Х
-2 O
2
-4

(3, - 2 )

Step-by-step explanation:

The solution is at the point of intersection of the 2 lines

The lines intersect at (3, - 2 ) ← solution

Check by substituting  x = 3 into the left side of the given equation

- 2(3) + 4 = - 6 + 4 = - 2 ← True

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
