Answer:
B
Step-by-step explanation:
The vertex is the turning point of the quadratic function.
In this case it lies on the x- axis at (2, 0 ) → B
Method 1:
Look at the picture.
is greater than
Method 2:
Find the common denominator:
multiples of 7: 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, ...
multiples of 9: 0, 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...
63 = 7 · 9
therefore
Y = -2x + b
Plug in the point
1 = -2(-3) + b
1 = 6 + b, b = -5
Solution: y = -2x - 5
Answer:-4
Step-by-step explanation:this is where the line crosses the x axis or the value when y=0
