3.) Write the equation of the line that passes through (0,3) and (1.-1) in standard form.

Given:

The points are (0,3) and (1,-1).

To find:

The equation of line passes through these points.

Solution:

Standard form of a line is

We know that, if a line passes through two points and , then the equation of the line is

The line passes through (0,3) and (1,-1), so the equation of the line is

Adding 4x and 3 on both sides, we get

Therefore, the standard form of the line is .

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.
