I'll help with a few because no-one wants to just do your homework
there is the formula way or the intuitive way
(-19, -2) (-17, -10)
now slope is (difference in y)/ (difference in x)
or
(y2 - y1)/(x2 - x1) the formula. where x2 just means the second x
<u>formula way:</u>
(-19, -2) (-17, -10)
(-10 - (-2))/ (-17 - (-19)) ReM: Negative on number and in the formula
(-10 + 2)/ (-17 +19) = -8/2 slope is - 8/2
<u>intuitive way</u>
(-19, -2) (-17, -10)
(difference in y)/ (difference in x)
lets looks at the ys
-2 and -10; how many steps from -2 to -10? -8 the diff in y
lets looks at the xs
-19 to -17; how many steps from -19 to -17? + 2 the diff in x
so its -8/2
Answer:
Y<= x+1

Answer:
11 hours
Step-by-step explanation:
Let's say Karen makes x hours babysitting and y hours giving music lessons.
Because she worked a total of 18 hours, we know that x + y = 18.
5 * x is how much money she earns babysitting for x hours, while 12 * y is how much money she earns giving music lessons for y hours. Adding them up gives her total revenue:
5x + 12y = 139
We now have a system of equations. Let's multiply both sides of x + y = 18 by 12:
12 * (x + y) = 18 * 12
12x + 12y = 216
Now, subtract 5x + 12y = 139 from 12x + 12y = 216:
12x + 12y = 216
- 5x + 12y = 139
_________________
7x + 0y = 77
Divide both sides by 7:
x = 11
Thus, Karen spent 11 hours babysitting.
