Answer:
- Using the y-axis to represent pounds, and the x-axis to represent kilograms, the graph is straight line going through the origin with a slope of 2.2 lbs/kg.
Explanation:
A constant conversion factor, such as 1 kg 2.2 lb, means that the two units are in direct proportion; thus the graph is a straight line that goes through the origin.
The conversion factor also gives the slope of the line.
Depending on which axis you choose for either unit the slope may be 2.2 pounds per kilogram, or 1/2.2 kilogram per pound.
When you use the y-axis for pounds and the x-axis for kilograms then the relationship is:
In that case, the slope is 2.2 pounds per kilogram.
<u><em>Answer:</em></u>
<u><em>Explanation:</em></u>
<u>The given equation is:</u>
To get the value of B, we will need to isolate it on one side of the equation
<u>This is done as follows:</u>
<u>1- Multiply both sides by 
to get rid of the fraction:</u>
<u>2- Add 25 to both sides of the equation:</u>
Based on the above:

Answer:
3x+2y+2=0
3x=-2y-2
x=-(2y+2)/3
Step-by-step explanation:
Answer:
y=7
Step-by-step explanation:
To calculate the standard equation of a line given two points, you need to calculate the slope and the y intercept.
The slope is the change in y variables over the change in x variables between two points.
(7-7)/(4-0)
that gives you a slope of 0, ie the line is horizontal. That means that the y value is going to be constant while the x value changes, so you can write the equation as y= y value in any point, so y=7.
