Step-by-step explanation:
Convert to the slope-intercept form (<em>y = mx + b</em>):
y - 2 = -(x + 1) <em>use the distributive property</em>
y - 2 = -x - 1 <em>add 2 to both sides</em>
y - 2 + 2 = -x - 1 + 2
y = -x + 1
We only need two points to plot the graph of the linear function.
Select any two x values. Insert them into the equation.
Calculate the value of y.
For x = 1:
y = -1 + 1 = 0 → (1, 0)
For x = 0:
y = -0 + 1 = 1 → (0, 1)
Now, to find how many people are not there, all you have to do is subtract the amount of seats and the people there.
112- 70= 42
Now since there are 7 seats per row and 42 is divisible by 7, you can divide 42 by 7.
42÷7= 6
So, 6 rows were empty.
You can find the answer by first dividing 12 by 6 which = 2
so multiply 36 by 2 which =72
72 is your answer ;) hope this helps
