Answer:
undefined
Step-by-step explanation:
x=-6 is a vertical line at x=-6.
Any vertical line has an undefined slope.
Let's pick two points on x=-6– (-6,1) and (-6,0)
(1-0)/(-6-(-6))=1/-6+6=1/0
Because you cannot divide by 0, a vetical line has an undefined slope.
Answer:
1.6/-8
Step-by-step explanation:
Rate of change is slope. So you need to use the slope formula: m=(y2-y1)/(x2-x1). You can decide which pairs will be 1 and 2 and will get the same answer, but keep the pairs together. So, if you do (3.6-2)/(-3-5) you will get 1.6/-8. If you needed to simplify to a fraction without a decimal you could do 1.6/-8 = .8/-4 = 8/10 x 1/-4 = -1/5.
If you graph this scenario, the number of gallons of gas left will be on the y-axis while the number of miles traveled will be on the x-axis.
The line will be going downwards as the miles get longer. This is because the number of gallons of gas left will decrease as Janelle drives farther.
Assuming that Janelle initially had 10 gallons of gas and 1 mile consumes 1 gallon.

Answer:
3pi or 9.42
Step-by-step explanation:
3/4x3.14x2x2=3pi or 9.42
Any equation in the form
Is a line. So, we only need to sample two points, and then connect them.
If we choose, for example, x=0 and x=3, we have
So, when x=0 then y=0, i.e. the line passes through the origin (0,0).
Similarly, when x=3 then y=2, i.e. the line passes through the point (3,2).
Connect these two points and you have the line.
