Write an equation in point slope form of the line that passes through the point (6,-5) and has the slope 1/2
babymother [125]

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question we have the final answer as

\huge y + 5 =  \frac{1}{2} (x - 6) \\

Hope this helps you

Kaitlin makes $13.15 per hour. If she works more than 40 hours in a week, she gets paid time and a half. Kaitlin gets a paycheck
Dmitrij [34]

Answer: 8 hours

Step-by-step explanation:

The pay is for 2 weeks which means that she worked for 80 hours.

At 80 hours, the regular income she should make is:

= 80 * 13.15

= $1,052

The total she made from overtime is therefore:

= 1,209.84 - 1,052

= $157.84

When she works overtime, she gets paid at a rate of a time and half. This means she gets:

= 13.15 * 1.5

= $19.73

The hours of overtime she worked is therefore:

= 157.84/19.73

= 8 hours
