Equation: y=-2x-4
slope: -2
y-int: -4
x-int: -2
Answer:
Y = (16 - 3x)/5
Step-by-step explanation:
3x + 5y = 16
subtract 3x from both sides:
16-3x = 5y
divide both sides by 5:
(16 - 3x) / 5 = y

Answer:
y = 3 · 2ˣ
Step-by-step explanation:
Exponential function is:
y = abˣ
Plug in the points:
⅜ = ab⁻³
12 = ab²
Solve the system of equations. Start by dividing the second equation by the first:
12 / ⅜ = (ab²) / (ab⁻³)
32 = b⁵
b = 2
Plug into either equation to find a:
a = 3
Therefore:
y = 3 · 2ˣ
