Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Explanation:

Step 1: Define

Point (0, -7)

Point (7, 0)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{0+7}{7-0}$
[Fraction] Add/Subtract: $\displaystyle m=\frac{7}{7}$
[Fraction] Divide: $\displaystyle m=1$

To calibrate the x-axis for 14C decay, you have to convert half-lives to number of years. Recall that 14C has a single half-life

hjlf

Answer:

d. 28,650 years

Explanation:

Since 14C has a single half-life of 5,730 years

The number of years that is going to make up 5 half-lives for 14C will be;

5,730 years × 5 = 28,650 years
