Which of the point-slope equations below are correct for the line that passes through points (-2, -2) and (2, 1)?

Ne4ueva [31]

Find slope first:
m =y2-y1/x2-x1
m = 1--2/2--2
m = 3/4

Select a point, insert your slope, & put it into point slope form:
y-y1 =m(x-x1)

Your final answers are:

y-1=3/4(x-2)
OR
y+2 =3/4(x+2)

Question:

Katy makes 48 cookies an hour. If she has 24 already, how long would it take her to make 120?

Answer:

It takes 2.5 hours for Katy to make 120 cookies

Step-by-step explanation:

Given:

Time taken to make 48 cookies = 1 hour

To Find:

Time taken to make 120 cookies = ?

Solution:

Time taken to make 48 cookies = i hour

So now time taken to make 1 cookie = $\frac{1}{48} hour$

So time taken to make 120 cookies

= Number of cookies X time taken to make one cookie

=> $120 \times \frac{1}{48}$

=> $\frac{120}{48}$

=> 2.5 hours
