Answer:
The answer to your question would be C) y = 3x + 2.
Step-by-step explanation:
The components of a slope intercept form equation is the slope and the intercept. The y-intercept is the term thats by itself which, is +2. This means that the line goes through positive 2 on the plane. For the slope, it is always the coefficient thats next to the x variable. In this case, its 3, meaning that the next point that the line will be on is every 3 steps up and 3 steps towards the right. Hope this helps!
If you have 8 yellow balloons for every 12 blue balloons, then if you have 20 balloons in total, 8 out of 20 of those balloons will be yellow. Then you can set up this ratio.
Then, you can use either cross multiplication or multiply the numerator and denominator by the same number to help solve for x. Personally, I prefer cross multiplication.
Finally, solve for x and if you had 100 balloons, you will have 40 yellow balloons.
