Answer:
y=(-5/6)x-7
Step-by-step explanation:
Let the line graph y=ax+b,
b=-7 as (0,-7) is y-intercept
To get a (slope), slope a = (y2-y1)/(x2-x1) = (-2-(-7))/(-6-0)=-5/6
Thus, y=(-5/6)x-7
9/8..... 9 friends divide 8 bags of apples evenly
.06=600
.06/.06=600/.06
$10,000=original price
but we still have to add tax
therefore,
$10,000+600=sale price
sale price=$10,600
Answer:
The slope of the line is 
.
Step-by-step explanation:
We are given two coordinate points:
We are asked to find the slope of the line.
We can use the rise-over-run formula to solve for the slope of the line.
However, we firstly need to name our coordinate points.
In math, we can label our coordinates using the following label system:
Therefore, we can also label our coordinates as such:
Now, we can supply these values into the formula and solve for our slope, or a better known variable, <em>m</em>.
Therefore, our slope is .
Answer:
The solution is (-2,4)
Step-by-step explanation:
We'll solve the system
2x+5y=16
-5x-2y=2
using elimination by addition and subtraction.
Let's eliminate x first. To do this, multiply the first equation by 5 and multiply the second equation by 2. We get:
10x + 25y = 80
-10x - 4y = 4
----------------------
21y = 84. Thus, y = 84/21 = 4.
Subbing 4 for y in the second equation, we get
-5x -2(4) = 2, or
-8 - 2 = 5x, or
-10 = 5x. Thus, x = -10/5 = -2.
The solution is (-2,4)
