Five pairs of points (X,Y) that satisfy the equation Y=-2X+5 may be the following:
For X=0: Y=-2*0+5=5 (0,5)
For X=1: Y=-2*1+5=3 (1,3)
For X=2: Y=-2*2+5=1 (2,1)
For X=3: Y=-2*3+5=-1 (3,-1)
For X=4: Y=-2*4+5=-3 (4,-3)
The slope of the function is m=-2. Correct answer: C
Its B
rise over run dictates that its 2/8 which simplifies to 1/4
and its at an upward angle from left to right therefore its positive.
Answer:
2nd - (w - 5)(w + 5)
4th - (-4v - 9)(-4v + 9)
Step-by-step explanation:
1. The first option shows an expression multiplied by its opposite(x -1), so therefore, it does not show the difference of squares
2. The second option does show the difference of squares because it is in the form (a + b)(a - b)
3. The third option is just a square because the same expression is multiplied by itself.
4. The fourth option is the difference of squares because it is in the form (a + b)(a - b). a equals -4v and b equals 9 in this case.
5. The fifth option is not the difference of squares. No term in common in both expressions
6. The sixth option is just a square because the same expression is multiplied by itself.
In all, there are two options that are the difference of squares, the 2nd and 4th.
