Answer:
Before we graph 
we know that the slope, mx, could be read as 
. To graph the the equation of the line, we begin at the point (0,0). From that point, because our rise is negative (-1), instead of moving upwards or vertically, we will move downards. Therefore, from point 0, we will vertically move downwards one time. Now, our point is on point -1 on the y-axis. Now, we have 2 as our run. From point -1, we move to the right two times. We land on point (2,-1). Because we need various points to graph this equation, we must continue on. In the end, the graph will look like the first graph given.
For the equation y = 2, the line will be plainly horizontal. Why? Because x has no value in the equation. The variable 
does not exist in this linear equation. Therefore, it will look like the second graph below. We graph this by plotting the point, (0,2), on the y-axis.
Answer:
24
Step-by-step explanation:
21 times 8 is 168, and 168 divided by 7 is 24, therefore she would need 24 to give among 21 friends if she still wanted to have 1/8 left over.
Answer:
24 Gallons
Step-by-step explanation:
We know his tank is 2/8 ths full. To get to 5/8ths we would have to add 3/8ths. If 3/8ths is equal to 9 then 1/8th would be equal to 3.
Answer: las option.
Step-by-step explanation:
The equation of the line in slope-intercept form is:
Where m is the slope of the line and b is the y-intercept.
Then function given in the problem has the form:
Where:
m=3
b=-2
Therefore, it is a linear function.
By definition, the domain of the linear functions that are not bounded, is all the Real numbers.
Therefore, the answer is:
<em> {x | x is a real number}</em>
