Answer:
We will graph the inequality in simplified form i.e 
The graph is shown in figure below
Step-by-step explanation:
Which is the graph of the linear inequality
(Note: Considering the inequality is 2y>-6 and x is typing mistake.)
First we will solve the inequality to find value of y
We have inequality:

For finding y we have to divide both sides of inequality by 2

Now, we will graph the inequality in simplified form i.e 
Inequality can be graphed on number line as well as graph paper.
Graph on number line
Since y is greater than -3, so all values greater than -3 will be included on the number line. An open circle will be drawn on -3, indicating -3 is not included but values greater than -3 are included. The figure A shows the graph
Graph on Graph paper
Since y is greater than -3, so all values greater than -3 will be included on the number line. A dotted line will appear on -3 and the region on right side of -3 (values greater than 3) will be shaded. The figure B shows the graph
Answer:

Step-by-step explanation:
using the image attached as reference
(-4,-1) - the -4 becomes x1, and the -1 becomes y1
(5,7) - the 5 becomes x 2 and the 7 becomes y2
plug this information into the equation
7-(-1)
m=----------
5-(-4)
solve
8
m=----------
9
so your slope would become 8/9
Answer:
Fahrenheit value for the highest temperature on the label should be 14°F.
Step-by-step explanation:
We are given that,
The alarm rings whenever the system temperature rises above -10°C.
It is given that the operators understand only Fahrenheit scale.
So, we will convert the highest temperature -10°C to Fahrenheit.
Since, we know,
(0°C × 9/5) + 32 = 32°F
Thus, we get,
(-10°C × 9/5) + 32 = (-18+32)°F = 14°F
Hence, the Fahrenheit value for the highest temperature on the label should be 14°F
