Please check for me this one!

OpenStudy (igreen):

1. Which equation from the three scenarios is in slope-intercept form? This one is correct.

OpenStudy (igreen):

Identify each of the following from the equation: m = b = This one is correct also.

OpenStudy (igreen):

2. Which equation from the three scenarios is in point-slope form? Correct

OpenStudy (anonymous):

yes!

OpenStudy (igreen):

Identify each of the following from the equation: The slope for this one is correct, but you left out \(\sf x_1\) and \(\sf y_1\).

OpenStudy (igreen):

\(\sf y - y_1 = m(x - x_1)\) Where \(\sf y_1\) is the y-value of the point, \(\sf x_1\) is the x-value of the point, and \(\sf m\) is the slope.

OpenStudy (igreen):

So do you know what \(\sf x_1\) and \(\sf y_1\) are from \(\sf y - 96 = 18(x - 5)\)?

OpenStudy (anonymous):

I honestly...don't know..:( Could you help me please?

OpenStudy (igreen):

Okay, look: \(\sf y - y_1 = m(x - x_1)\) \(\sf y - 96 = 18(x - 5)\) They're going to be in the same place as \(\sf y_1\) and \(\sf x_1\).

OpenStudy (anonymous):

Hmm...can you give me the answer? I'm kinda clueless...Sorry

OpenStudy (igreen):

\(\sf y - \color{red}{y_1} = m(x - \color{blue}{x_1})\) \(\sf y - \color{red}{96} = m(x - \color{blue} 5)\)

OpenStudy (igreen):

This is correct.

OpenStudy (igreen):

3. Which equation from the three scenarios is in standard form?

OpenStudy (igreen):

But the others are incorrect.

OpenStudy (igreen):

Standard Form: \(\sf \color{red}Ax + \color{blue} By = \color{lime} C\)

OpenStudy (igreen):

\(\sf \color{red} 4x + \color{blue} 1y = \color{lime}{40}\)

OpenStudy (igreen):

Yep, you got it!

OpenStudy (igreen):

Sure

OpenStudy (anonymous):

Please let me know if I'm correct and let me know if there's something that I need to check on!

OpenStudy (igreen):

First two are correct.

OpenStudy (igreen):

Last one is also correct.

OpenStudy (igreen):

Looks good.

OpenStudy (anonymous):

For the problem part, did I do right? And how about the screenshot?

OpenStudy (anonymous):

is there anything that I need to fix?

OpenStudy (igreen):

Nope

OpenStudy (anonymous):

Ok...Thanks!
