Write an equation in standard form of the line that passes through the given point and the given slope. (-9, -4); m = -1/3

tigry1 [53]

<h2>Answer:</h2>

First, we must determine <u><em>b</em></u> using <u><em>slope-intercept form*</em></u>, the given point, and the given slope.

$-4 = -\frac{1}{3}(-9) + b\\\\-4 = -3 + b\\\\-1 = b$

Second, we need to set up the equation of the line in slope-intercept form.

$y = -\frac{1}{3}x - 1$

Third, we convert the above equation to <em>STANDARD FORM**</em>.

$y = -\frac{1}{3}x - 1\\\\\frac{1}{3}x + y = -1$

We now have our equation: $\frac{1}{3}x - y = -1$

*Slope-intercept form: <em>y = mx + b</em>

**Standard form: <em>ax + by = c</em>

Megan took out a student loan for $9,075 if she paid $4.537.50 in simple interest over 10 years what percent was her interest ra

madam [21]

Answer:

Step-by-step explanation:

Solving our equation

r = 4537.5 / ( 9075 × 10 ) = 0.05

r = 0.05

converting r decimal to a percentage

R = 0.05 * 100 = 5%/year

The interest rate required to

accumulate simple interest of $ 4,537.50

from a principal of $ 9,075.00

over 10 years is 5% per year.
