Every time the y-value decreases by 1, the x-value increases by 2, so the slope is -1/2 throughout the line.

Answer:

The slope is fraction negative 1 over 2 throughout the line.

Step-by-step explanation:

The slope (m) of a line is computed as follows

m = (y2 - y1)/(x2 -x1)

where (x1, y1) and (x2, y2) are the coordinates of 2 points of the line. Taking, for example, points (0, 0) and (-4, 2), the slope is:

m = (2 - 0)/(-4 -0)  = -1/2

Then, the slope is -1/2 throughout the line.

Ramon earns $1,735 each month and pays $53.10 on electricity. To the nearest tenth of a percent, what perfect of ramons earnings
Alenkinab [10]

Answer:

\boxed{3.1 \, \%}

Step-by-step explanation:

The formula for calculating percentage is

\text{Percentage} = \dfrac{\text{Part}}{\text{Whole}} \times 100 \, \%

The "part" is the electricity payment.

The "whole" is Ramon's earnings.

\begin{array}{rcl}\text{\% of earnings} & = & \dfrac{53.10}{1735} \times 100 \, \% \\\\& = & \mathbf{3.1 \, \%}\\\end{array}\\\boxed{\mathbf{3.1 \, \%}} \text{ of Ramon's earnings are on electricity}
