Answer:
1
Step-by-step explanation:
12+[2-(4 × a²)] ÷ 7+b
= 12+[2-(4 × 5²)] ÷ 7+ 1
= 12+[2-(4 × 25)] ÷ 7+ 1
= 12 + (2 - 100)÷ 7 + 1
= 12 - 98 ÷ 7 + 1
= 12 - 14 + 1
= 1
So the equation of a line is y=mx + b.
In order to find the slope given only two coordinates we have to use a formula to find slope. It is:
y2-y1/x2-x1.
So let’s get all the values first from (3,4) and (2,-1).
y2= -1
y1=4
x2=2
x1=3
Plug in the values now.
-1 - 4 = -5
-5/2-3=5
The slope is 5x.
Now let’s find the y intercept, to find the y intercept, we have to do a formula which is:
y-y1=m(x-x1)
So let’s plug in the values.
y-4=5(x-3)
y-4=5x-15
+4 +4
y=5x-11
The final answer is y=5x-11!!!

Using the given bar graph, it is found that the statement that is supported by the data in the bar graph is given by:
The number of employees in Category I is three times the number of employees in Category II.
<h3>What does the bar graph state?</h3>
Research the problem on the internet, it is found that:
- 45% of the employees are of Category I.
Hence the correct option is given by:
The number of employees in Category I is three times the number of employees in Category II, as 45% = 3 x 15%.
