The table below shows the relationship between the number of teaspoons of baking powder in a mix and the height of fudge brownie

rosijanka [135]

Answer:

Option A. $y=0.28x+0.75$

Step-by-step explanation:

Let

y -----> the height of fudge brownies in centimeters

x ----> teaspoons of baking powder

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take the points

(5,2.15) and (6,2.43)

substitute the values

$m=\frac{2.43-2.15}{6-5}$

$m=\frac{0.28}{1}=0.28$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=0.28$

$(x1,y1)=(5,2.15)$

substitute

$y-2.15=0.28(x-5)$

Isolate the variable y

$y-2.15=0.28x-1.4$

$y=0.28x-1.4+2.15$

$y=0.28x+0.75$
