Answer:
y = 3x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3)
m =
= 3
We are given the y- intercept, that is c = 3
y = 3x + 3 ← equation of line
4x3=12. Think of it like this... 4 times as many as 3 is 12 (x)
(=)
So 4 times is 4 multiplied by....... 3 is just 3.... is means equals.... and the answer is 12. Your welcome, I hope I helped.
I don't know how to solve this but you can go to desmos.com and it will graph it for you.
Hope this helps make your life easier!
I think the ratio is for for every 4 packs it cost 10 dollars so in all it would cost 30 dollars
