Slope of the line is calculated by the formula:

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

We have the points ( -2 , 4) and (3 , -5) so plug in the values in the formula:

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-5-4}{3-(-2)}\\\\m=\frac{-9}{5}\\$

so the slope(m) equals -9/5

where p is the original amount.
R is the amount of percentage compounded
N is amount of times compounded per year.
T is how long the interest last.

P is 400,00p

T is 12% or 0.12

N is 4 since it is compounded quarterly

$400000(1 + \frac{0.12}{4} ) {}^{20}$

Ypu get
