Slope = change in y over change in x:
Slope = (-6 6) / 2- -6) = -3/2
Equation of a line is y = Mx + b, where m is the slope and b is the y intercept.
Y = -3/2x + b
Replace y and x with one of the given points and solve for b:
6 = -3/2(-6) + b
6 = -9 + b
B = -9 + 6
B = -3
The equation of the line is y = -3/2x-3
<span>4x + 3y = 12
-2x - 5y = 1
multiply bottom by 2
</span><span>4x + 3y = 12
-4x - 10y = 2
add both equations
-7y = 14
divide by 7
y = -2
plug into first equation
4x + 3(-2) = 12
solve for x
4x = 18
x = 4.5

Answer:
$16
Step-by-step explanation:
$2 x 5 = $10
1 pound = $9
2/3 = $6
10+6=16
This is number 8. the second person got number 9
