Which system of equations is graphed on the coordinates below

Crazy boy [7]

Answer:

Step-by-step explanation:

Blue line:

$(-4, 0), (0, -2) \\m = \frac{\triangle y}{\triangle x} = \frac{0 - (- 2)}{-4 - 0} = \frac{2}{-4} = -\frac{1}{2}\\\text{y-intercept (c) is when x = 0}\\x = 0 \rightarrow y = -2\\y = mx + c\\y = -\frac{1}{2}x - 2\\2y = -x - 4\\x + 2y = -4$

Red line:

$(5, 0), (0, -5) \\m = \frac{\triangle y}{\triangle x} = \frac{0 - (- 5)}{5 - 0} = \frac{5}{5} = 1\\\text{y-intercept (c) is when x = 0}\\x = 0 \rightarrow y = -5\\y = mx + c\\y = 1x - 5\\y - x = -5\\-y + x = 5\\x - y = 5$

A student skipped a step when she tried to convert 18 hours into seconds,

gladu [14]

Answer:

The conversion of minutes to seconds is skipped in multiple-step conversion.

Step-by-step explanation:

Given:

To convert 18 hours into seconds.

Now, to get the conversion ratio skip in this multiple-step conversion.

First we need to convert hours into minutes:

1 hour = 60 minutes.

So, 18 hours = $18\times 60 minutes$

= $1080 minutes$ .

Then, we convert minutes into seconds:

1 minute = 60 seconds.

So, 1080 minutes = $1080\times 60 seconds$

= $64800 seconds$ .

Thus, 18 hours = 64800 seconds.

<u>As given in question the conversion from hours to seconds is there but the conversion of minutes to second is not there it is skipped so the result is incorrect.</u>

Therefore, the conversion of minutes to seconds is skipped in multiple-step conversion.
