Divide -81 by 27. You get -3.

Divide 27 by -9. You get -3.

Divide -9 by 3. You get -3.

Every new term is the previous term multiplied by -3.

Multiply -81 by -3: -81 * (-3) = 243

Multiply 243 by -3: -3 * 243 = -729

Answer: 243, -729

Each equation represents a linear relationship. Examine each and determine the slope and y- intercept

marysya [2.9K]

Answer:

Slope is -3/7. Y intercept is 250/7.

Step-by-step explanation:

Since they asking for the slope and y intercept, let put it in slope intercept form.

$y = mx + b$

where m is the slope and b is the y intercept.

The equation given is in standard form so we will convert it to slope intercept.

$3x + 7y = 250$

$7y = 250 - 3x$

$y = \frac{250}{7} - \frac{3}{7} x$

$y = - \frac{3}{7} x + \frac{250}{7}$

The slope is -3/7

The y intercept is 250/7
