Answer 2

Option A.
`y=0.28x+0.75`

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=(y2-y1)/(x2-x1)`

take the points

(5,2.15) and (6,2.43)

substitute the values

`m=(2.43-2.15)/(6-5)`

`m=(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`
