Answer:
9
Step-by-step explanation:
8 times 9 is 72
80 times 9 is 720
720 divided by 9 is 80
Answer:
This is what it should look like:
Given:
The table of values is:
x : -7 -5 -3 -1
y : 5 9 13 17
To find:
Whether the given data is linear and then find the equation.
Solution:
The given data is linear if the slope and rate of change is constant.
Slope formula:
Using the slope formula. we get
Since the rate of change is constant, i.e., 2, therefore the given data is linear.
The slope of a linear equation is 2 and it passes through the point (-7,5). So, the equation of the line is:
Adding 5 on both sides, we get
Therefore, the equation for the given data is .
h = 5 because if you added 8 to the other side of the equation, then the equation would be in vertex form, where the opposite of h, and the value of k (8) is your vertex. So, we know that the x-value of the vertex is also the axis of symmetry, so the axis of symmetry is also the x-value of the vertex, or h.
Hope this helps! :)
