You can immediately read off the y-intercept; it is (0, -1).
To find the slope:
-3 - 0
m = ---------- = -1/3

Idk I have tried and failed miserably
Answer: The answer is b=1/4
Answer:
$19.68
Step-by-step explanation:
this is not really clearly defined.
I assume it means that they are buying the item, no matter how much it costs, and that the split ratio between them also remains the same no matter the actual cost.
x = what Marcia is paying
and 132 - 18% = 132 × (100 - 18) / 100 = 132×0.82 = 108.24
so,
x + x/2 + x/3 = 108.24
6x + 3x + 2x = 649.44
11x = 649.44
x = $59.04
Mario's part is x/3 = 59.04/3 = $19.68
Ok so
log₁₂₅25
remember
logₐy=x means aˣ=y
and
remember that (xⁿ)ᵇ=xⁿᵇ
and
if aⁿ=aᵇ where a=a, then n=b
so
log₁₂₅25=x means
125ˣ=25
to solve, convert to same base
125=5³
25=5²
(5³)ˣ=5² means
5³ˣ=5²
therefor
3x=2
solve
divide both sides by 3
x=2/3
answer is C
