Y = kx
Where 'k' is the constant of variation.
y = 4x means that 4 is the constant of variation.
Answer: 4
Answer: 72.8%
Step-by-step explanation:
First find the slope.
We know these two points are in the line: (0,8) and (6,5)

The slope is -1/2. The y-intercept can be found when x = 0. And we know that the point (0,8) is on the line and x = 0, therefore the y-intercept is 8.
Plugging this into the slope-intercept form which is
y = mx + b, where m is the slope and b is the y-intercept, we get:
y = (-1/2)x + 8
Answer:
8
Step-by-step explanation:
Fourmla:
a^2+b^2=c^2
7^2=49
3^2=9
49+9=58
square root of 58 is about 8.
9) is 3. Drink = 3$. 18-3 = 15. 15 equals 5 candy bar so each bar is 3
