Graph a line that contains the point (4,3) and has a slope 1/2

Roman55 [17]

Answer: The graph is attached.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

We can find "b" substituting the slope and coordinates of the (4,3) into thte equation $y=mx+b$ , and then solving for "b":

$3=\frac{1}{2}(4)+b\\\\3-2=b\\\\b=1$

By definition, the line intersects the x-axis when "y" is zero.

Then, we need to substitute the y-intercept and $y=0$ into $y=mx+b$ and then solve for "x" in order to find the x-intercept:

$0=\frac{1}{2}x+1\\\\-1(2)=x\\\\x=-2$

Knowing the x-intercept and the y-intercept, we can graph the line (The graph is attached)

To begin a bacteria study, a petri dish had 2800 bacteria cells. Each hour since, the number of cells has increased by 7.2%. Let

Rudiy27

The function that models exponential growth is:

P(t) = P0*(1 + r)^t, where

P0 = P(0) is the initial value of P

r is the growth rate as a decimal

In our case we have:

P(0) = 2800

r = 0.035 or 3.5%

P(t) = 2800*(1 + 0.035)^t

P(t) = 2800*(1.035)^t

The same exponential function written using y and t is:

y = 2800*1.035^t.
