8 teaspoons, you make the ratio 1:2. then fill it in as x:16, for every 1 teaspoon of vinager you have 2 of mayo. so you'd need to make sure than x, would make 1:2 true. 8:16 is the solution because reduced it is 1:2.

The y-intercept of the first question is 1 and it represents the number of minutes they stretch when they don't jog.
#4) y=1/2x + 1
#5) 10 cakes, because y=9/10x+1
Explanation
For the first question: The y-intercept is easily picked from the two points that define the line. (0, 1) would have to be on the y-axis, because when we plot it, the x-coordinate is 0. This means it is the y-intercept of the line.
#4) Finding the slope of the line, we use the formula
m=(y₂-y₁)/(x₂-x₁) = (3-1)/(4-0) = 2/4 = 1/2
The y-intercept is at (0, 1), using the same justification as the first question.
This gives us the equation y = 1/2x + 1.
#5) First we find the equation of the line. To do this, find the slope:
m=(y₂-y₁)/(x₂-x₁) = (10-1)/(10-0) = 9/10
The y-intercept is at (0, 1). This makes our equation y=9/10x + 1.
Using 10 as x (x represents the number of weeks) we have
y=9/10(10) + 1
y=9/10(10/1) + 1
y=90/10 + 1
y=9+1 = 10
