Answer:
Step-by-step explanation:
Let the equation of the line given in the graph is,
y = mx + b
Where 'm' is the slope of the line
And 'b' represents the y-intercept
Since slope of a line passing through two points and
is modeled by,
m =
If this line passes through (-3, 3) and (3, -1),
m =
m =
=
And 'b' = 1
Equation of this line will be,
Answer:
2.625 cups or 21 ounces
Step-by-step explanation:
Ava needs 3/4 cup of blue paint for every 1 cup of white paint. So, the ratio is 0.75 : 1.
She has 28 ounces of white paint. But, you have to convert ounces to cups.
1 cup = 8 ounces
28 ounces ÷ 8 ounces/cup = 3.5 cups
Now set up a ratio.
X (how much blue paint is needed) is over 3.5 cups (the amount of white paint she has)
Cross multiply and divide.
x = 0.75 × 3.5
x = 2.625 cups
To convert to ounces, multiply by 8.
2.625 cups × 8 ounces = 21 ounces
Therefore, Ava needs 2.625 cups or 21 ounces of blue paint.
Hope that helps.
