X+6y=12
6y=12-x
y=12/6- x/6
y=(-1/6)(x)+2
The missing exponent is 2
To find the rate of change, or slope, pick two points. The slope, is change in y coordinates over change in x coordinates.
![slope = \frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=slope%20%3D%20%20%5Cfrac%7By2-y1%7D%7Bx2-x1%7D%20)
.
In this case, the slope is
![\frac{-11+1}{2-0} = \frac{-10}{2} = -5](https://tex.z-dn.net/?f=%20%5Cfrac%7B-11%2B1%7D%7B2-0%7D%20%3D%20%20%5Cfrac%7B-10%7D%7B2%7D%20%3D%20-5%20)
.
Remember that subtracting a negative number equals adding the number without the negative sign.
a-(-b) = a+b
Now for the y-intercept. The y-intercept is where the graph intersects the y-axis, where x = 0.
You have the coordinate (0, -1), where x = 0. So the y-intercept is -1.
Putting these values into the slope-intercept form y = mx+b, the equation is
y = -5x - 1
Answer:
.90(85.00) would give the same result
Step-by-step explanation:
Rhonda is using the total cost of the item ($85.00) multiplied by the discount (10%) to find the total discount: 85 x 0.10 = 8.50. Once Rhonda subtracts the discount ($8.50) from the total: $85 - $8.50 = $76.50. The other way to look at the problem, is that Rhonda is only paying for 90% of the total cost of the items, instead of 100% since she is receiving the 10% discount. So, she would get the same final total by multiplying the cost of the items ($85.00) by 90%, or 0.90.
