1. What is an equation of the line with slope 6 and y-intercept -4? Which equation represents the line shown? Please note that anyone who answers this post with random letters and or numbers that have nothing to do with this mathematics problem will be deleted or reported.

1.  y = 6x - 4

2.  y = 5x - 3

Step-by-step explanation:

1. Since 6 is the slope, you just add the x after the 6. The y - intercept always goes at the end of the equation.

2. The y - intercept is - 3 and the slope is 5 over 1 which is just 5.

There are 3 green marbles in the box.

Step-by-step explanation:

15% = 0.15

To figure out how much 15% of 21 is, you must multipl the decimal form of the percentage by the whole number. This will give you how much of that number that percentage is.

0.15 * 21 = 3.15  

But you can't have 0.15 of a marble, so you must round as well.
