The slope is -4

The graphing equation is y=-4x-16

Step-by-step explanation:

Change in y is -4--8= -4+8 = 4

change in x is -3--2= -3+2= -1

rise over run is 4/-1

The slope equals -4

y=-4x+b (now enter one of the points and solve for b since that is the y intercept)

(-3,-4). y=mx+b or -4=-4 × -3+b, or solving for b: b=-4-(-4)(-3). b=-16

4y - 6 + y^2 - 9 = y^2 + 4y - 15

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
