Answer:

Answer: y - 8 = x - 7

Step-by-step explanation:

SOLUTION:

General equation : (y2 - y1)/(x2 - x1) = slope

.

Substitute slope = 1 into the equation:

(y2 - y1)/(x2 - x1) = 1

.

Substitute (7, 8) into the equation:

(y - 8)/(x - 7) = 1

.

Cross multiply:

y - 8 = x - 7

.

Answer: y - 8 = x - 7

I really hope dis Helps :D

Answer:

1x - y + 1 = 0

Step-by-step explanation:

The equation for the point-slope equation is y - y1 = m(x - x1). Substitute y1 for 8, m for 1, and x1 for 7. Keep y & x as they are.

y - 8 = 1(x - 7)

<em>Use the distributive property to multiply 1 by x - 7.</em>

y - 8 = 1x - 7

<em>Now, add 8 to both sides.</em>

y = 1x - 7 + 8

<em>Add 8 to -7 to get 1.</em>

y = 1x + 1

<em>Now convert that into point slope form by doing the following: Split "1x + 1" by putting -y (opposite of y) in the middle of the left side, and then putting 0 on the right.</em>

1x - y + 1 = 0

The point slope equation of the shown question is 1x - y + 1 = 0.

At a particular music store, CDs are on sale at $14.00 for the first one purchased and $12.00 for each additional disc purchased
Delicious77 [7]
To calculate the answer, we subtract $ 14 from the first CD to the total amount spent, which is $ 86.
 So:
 $ 86- $ 14 = 72
 The rest of the CDs cost $ 12.
 Then we divide $ 72 between $ 12
 $ 72 / $ 12 = 6.
 That means that 6 CDs were bought at $ 12 plus the first one bought at $ 14.
 So the number of CDs that María bought was 7
