Use the coordinates of the labeled point to find a point-slope equation of the

notsponge [240]

Answer:

B. $y + 5 = 2(x + 2)$

Step-by-step explanation:

Point-slope equation is given as $y - b = m(x - a)$ , where,

(a, b) = (-2, -5)

$m = slope = \frac{y_2 - y_1}{x_2 - x_1}$

Using two points on the line (-2, -5) and (0, -1),

Slope (m) = (-1 -(-5))/(0 -(-2)) = 4/2

m = 2

✔️To write the equation in point-slope form, substitute a = -2, b = -5, and m = 2 into $y - b = m(x - a)$

Thus:

$y - (-5) = 2(x - (-2))$

$y + 5 = 2(x + 2)$

Sophie deposited money into an account in which interest is compoundedsemiannually at a rate of 2.4%. She made no other deposits

meriva

Given

Compounded semiannually

rate = 2.4%

time = 11 years

Future Value = $11,227.78

$\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ \frac{A}{(1+\frac{r}{n})^{nt}}=\frac{P(1+\frac{r}{n})^{nt}}{(1+\frac{r}{n})^{nt}} \\ P=\frac{A}{(1+\frac{r}{n})^{nt}} \\ P=\frac{11227.78}{(1+\frac{0.024}{2})^{2(11)}} \\ P=\frac{11227.78}{1.012^{22}} \\ P=8636.20 \end{gathered}$

Rounding to the nearest whole number, the amount the she has deposited is $8636.
