Answer:
B
Step-by-step explanation:
Although you didn't provide a list of options to choose from, I hope my explanation will help you work this out with ease. :)
This equation is in a form known as "standard form." ax+by=c Standard form is commonly used, however for comparing slopes, there is a more efficient equation to use.
Point-slope form (y=mx+b) allows lines' slopes (y) and y-intercepts (b) to be quickly compared and contrasted. Let's put the equation into this form.
2x-y=-1
-2x -2x
-y = -1 - 2x
*-1 *-1
y= 1 + 2x
Switch pieces around
y= 2x + 1
The slope is 2, the y intercept is 1.
<h2><u>Any line that rises 2 units up for every one unit right and that crosses over the vertical axis at any point other than 1 is your answer.</u></h2>

Answer:
the third option
Step-by-step explanation:
by shifting it up 3, you just add 3 to -7 which is -4
by shrinking it a factor of 1/2, you multiply -2 by 1/2 which is -1
Using simple interest, it is found that her interest charge this month will be of $30.
<h3>Simple Interest</h3>
Simple interest is used when there is a single compounding per time period.
The amount of interest after t years in is modeled by:
I(t) = Prt
In which:
- r is the interest rate, as a decimal.
In this problem, considering the time in years, the parameters are:

Hence:

Her interest charge this month will be of $30.

Answer:
There will be 5 kilometers between each rest stop
Step-by-step explanation:
Ok, so there are two rest stops at the start and end of the trail. This means that the sum of the distances of the rest stops must equal 20 kilometers.
If you can imagine a number line being split by 3 lines, it makes four segments.
We can't solve this using
because that would mean one of the three rest stops is at the end of the hike
So,
