Answer:
y = - 
x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - and c = - 8, hence
y = - x - 8 ← linear equation
Answer:
you saved $3.20
Step-by-step explanation:
16 x 20/100
16 x 0.2
= 3.20
so 16-3.20= 12.80
final price is 12.80
Answer:
69
Step-by-step explanation:
Answer:
2 =x
Step-by-step explanation:
f(x) = 9 - 4x
Let f(x) = 1
1 = 9 -4x
Subtract 9 from each side
1-9 = 9-4x-9
-8 = -4x
Divide by -4
-8/-4 = -4x/-4
2 =x
M =kw+b general form
1. k should be negative because the line is going down when x increases
2. b is y intercept , b=250
slope= - 50/2 =-25
m=-25w + 250
correct choices
1) m=250-25w
4) m +25w=250, because can be written as m=-25w =250
