The answer is 7.14%
Your ruler measuring centimeters has lines for each centimeter. The rule for error is anything between 6.5 and 7.5 is considered 7cm. So the degree of error is plus or minus .5cm.
Your aim is 7cm so you divide your error of .5 by your target measurement. .5/7= 7.14 percent.
Both powers should be in the denominator with positive exponents.

Step-by-step explanation:
Answer:
y-intercept = (0, - 3)
x-intercept = (-6, 0)
slope = - 1/2
Step-by-step explanation:
The y intercept is the value of y when the x = 0. By looking at the graph, we can tell that when x = 0, y = - 3. Likewise for the x-intercept.
We can use the slope formula to determine the slope.
m = y2 - y1/ x2 - x1
You can choose any 2 points on the line and substitute in the formula. I chose the y and x intercepts for easier calculations.
m = - 3 - 0/ 0 - (- 6)
m = - 3/ 6
m = - 1/2
I think it would be 25 ways
