Find The slope of the line described<br> by x+2y=8

Harman [31]

Answer:

$Slope = m = \frac{-1}{2}$

Step-by-step explanation:

The equation of a line in slope-intercept form is.

$y = mx + b$ ----->(eq 1)

∴ m is slope

$x+2y=8$

subtract x from both sides.

$x - x +2y= - x + 8$

$2y= - x + 8$

divide - 2 on both sides

$\frac{2y}{2} = \frac{ - x + 8}{2}$

$y = \frac{ - x}{2} + \frac{8}{2}$

$y = \frac{ - 1}{2}x + 4$ ----->(eq 2)

By comparing (eq 1) and (eq 2)

$m = \frac{-1}{2}$

$Slope = m = \frac{-1}{2}$

If you already know that you have . . .

1$ after week 1
2$ after week 2
4$ after week 3
8$ after week 4

. . . You can then tell that every week the money you save doubles (times 2)

So to continue . . . .
16$ after week 5
32$ after week 6
64$ after week 7
128$ after week 8
256$ after week 9
512$ after week 10

You will then know that after ten weeks u will have 512$ which is answer choice D.

Hope this helps! :)
