Answer:
Slope = -1
Step-by-step explanation:


Substitute values into the given equation


Solution:
<u>Note that:</u>
- Robert + b = Jack
- Robert = 99 buttons
<u>Substituting the values into the equation:</u>
- Robert + b = Jack
- => 99 + b = Jack
This means that Jack has 99 + b buttons.
Answer:
11. 16x +(9x+5)= 180
25x + 5 = 180
25x= 175
x= 7
If x is 7, then the top value is equal to the bottm one becuase they are vertical angles.
112 + 4y= 180
4y = 68
y= 17
Step-by-step explanation:
12. 6x - 11 + 2x - 9= 180
8x - 20= 180
8x= 200
x= 25
6(25) - 11= 139
20y + 19 = 139
20y = 120
y=6
Answer:
y=2/3x-3
Step-by-step explanation:
using y=mx+c
since the intercept is negative,it affects the positive sign
Answer:
Add the two x-coordinates and divide by 2 and the same thing for y-coordinates....takes two coordinates must be the ones that are the end points of the line
