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)

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

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

Oduvanchick [21]

Answer:

Blue grape in most expensive

Step-by-step explanation:

Given:

Amount of blue grapes = $18

Number of blue grapes = 4 bags

Amount of green grapes = $6.04

Number of green grapes = 2 bags

Find:

Which grape in most expensive

Computation:

Cost of blue grapes = 18 / 4

Cost of blue grapes = $4.5

Cost of green grapes = 6.04 / 2

Cost of green grapes = $3.02

Blue grape in most expensive
