2. Write the following in the y=mx+ b form. Show all work.
a) - 2x + y = 8

Answer

- 2x + y = 8

+2x. + 2x

y = 2x + 8

hope this helps :)

Step-by-step explanation:

If we want to find the equation in slope-intercept form, or y=mx+b (m is the slope and b is the y-intercept), we must isolate y on one side of the equation.

We are given the equation:

-2x is being added to y. Since it is negative, we should add 2x to both sides of the equation.

According to the Commutative Property of Addition, we can switch 8 and 2x so it is in the form y=mx+b.

The equation is y=2x+8 (the slope, m, is 2 and the y-intercept, b, is 8).

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
