Write an equation that passes through the points (3, 6) and (1,-1)

Marina CMI [18]

Finding gradient:

m = y2 - y1
x2 - x1

= -1 - 6
1 - 3

= -7 / (-2)
= 7/2

y = m(x - x1) + y1
y = 7(x - 3) + 6
2
2y = 7x - 21 + 12
2y = 7x - 9

Answer:

$\$164.5$

Step-by-step explanation:

Bonnie deposits $70.00 into a new savings account.

The account earns 45% simple interest per year.

She neither added or removed from the savings account for 3 years.

We know that,

$i=\dfrac{P\cdot r\cdot r}{100}$

here,

i = interest,

P = principal = $70,

r = rate of interest = 45%,

t = time = 3 years,

Putting the values,

$i=\dfrac{70\cdot 45\cdot 3}{100}=\$94.5$

So the total amount will be,

$=\text{Principal}+\text{Interest}$

$=70+94.5$

$=\$164.5$
