## Identify both the x- and y-intercepts of the linear equation graphed on the coordinate plane above. Use the intercepts to write an equation of the line in point-slope form, slope-intercept form, and general form of a linear equation.Complete your work in the space provided or upload a file that can display math symbols if your work requires it. In your work, be sure to include the coordinates for both intercepts and the equations of the line in all three formats.

The x int (where the line crosses the x axis) is (-2,0)
the y int (where the line crosses the y axis) is (0,-2)

(-2,0)(0,-2)
slope = (-2 – 0) / (0 – (-2) = -2/2 = -1

y = mx + b
slope(m) = -1
use either of ur points (-2,0)…x = -2 and y = 0
sub and find b
0 = -1(-2) + b
0 = 2 + b
-2 = b

so ur equation in slope intercept form is : y = -x – 2

y = -x – 2
x + y = -2
x + y + 2 = 0 <== general form

there can be 2 answer for point slope form…
y – y1 = m(x – x1)
slope(m) = -1
(-2,0)…x1 = -2 and y1 = 0
sub
y – 0 = – (x – (-2)
y – 0 = -(x + 2) <=== point slope form

y – y1 = m(x – x1)
slope(m) = -1
(0,-2)…x1 = 0 and y1 = -2
sub
y – (-2) = – (x – 0)
y + 2 = – (x – 0) <== point slope form

## 18. Which of the following instruction formats illustrates a task using pictures? if-then table list paragraph diagram

The sentence that correctly uses commas to separate items in the list is number 3, “The deacidification process preserves pages by neutralizing acid with magnesium oxide, raising the pH level of the paper, and minimizing the alkaline reserve.”

There are three things that preserve pages in the deacidification process:

1. neutralizing acid with magnesium oxide
2. raising the pH level of the paper
3. minimizing the alkaline reserve

Therefore, these three items make up are list. Commas are used after every item in a list. However, a comma is not needed after the last item in a list. Of the available options only, number 3 uses the commas in the correct places as seen below:

“The deacidification process preserves pages by neutralizing acid with magnesium oxide, raising the pH level of the paper, and minimizing the alkaline reserve.”

Technically, number 4 could also be correct. An Oxford comma is the last comma in a list. Some people choose to not use the Oxford comma. It is generally accepted as correct, although it can sometimes cause confusion when not used. The elimination of the Oxford comma can be seen below:

The deacidification process preserves pages by neutralizing acid with magnesium oxide, raising the pH level of the paper and minimizing the alkaline reserve.
