Answer:

-12 = 3x - 4y

Step-by-step explanation:

Two points on the graph are (-4, 0) and (0, 3).  Moving from the first point to the second, we see x (the 'run') increase by 4 and y (the 'rise') increase by 3.  Thus, the slope of this line is m = rise / run = 3/4.

Using the point slope form, we get:

y - 3 = (3/4)(x - 0), or

4y - 12 = 3x, or

-12 = 3x - 4y (which is in Standard Form).

When painting my bedroom I used 3 1/2 liters of blue paint and 2 1/4 liters of red paint. How much paint did I use in all
Lubov Fominskaja [6]
Hi there!

To solve this problem, we need to find the total amount of paint used by adding the two fractions.

First, we need to find the common denominators below adding.

1/2 = 2/4
1/4 = 1/4

The common denominator is 4.

Now, we add the mixed numbers together:

3 2/4 + 2 1/4 = 5 3/4

Since 5 3/4 can't be simplified, the answer is:

5 3/4 liters of paint

Hope this helps!
