Answer: The answer would be B

<u>Write out the equation in slope-intercept form: </u>

y=-5/3x+6 (Once we know that, it'll be easier to convert it into standard form.)

<u>Subtract -5/3 from both sides of the equation:</u>

y+5/3x=6

<u>Subtract 6 from both sides:</u>

y+5/3x-6=0

<u>Multiply both sides by 3 to get rid of the fraction:</u>

3y+5x-18=0

<u>Then arrange the numbers to x and y are on one side by itself:</u>

3y+5x=18

<em>And that's your answer!</em>

Answer: -3, -2.5, -1, 2, 5.

Explanation:
The number line goes from the smallest number to the largest number. As an example you may ask why -3 is smaller than -1 even though it looks larger. This is because it actually isn’t since it is negative. When a number is negative, the higher the number are the smaller it is. One more example could be that -10 is smaller than -5.
