Equation of a line:  y = mx + c,  where m is the slope and c is the y-intercept. To calculate the slope, we do so using the formula: m = \frac{y2 - y1}{x2 - x1}

Now plugging in our values, m = \frac{4 - (-3)}{-7 - (-2)}  = \frac{4 + 3}{-7 + 2} = \frac{7}{-5} = \frac{-7}{5}

So our slope m, is = -7/5

We can now input the value of the slope. But in this question, we cannot use the above equation of a line since we are asked to use a point-slope equation expression, so the equation is y - y1 = m(x - x1)

Now we plug in our values,

y - (-3) = \frac{-7}{5}(x -  (-2))\\y + 3 = \frac{-7}{5}(x + 2)

So the answer should be option D.

What does 6-2p+5p-3 equal
viva [34]

Answer:

3 + 3p

Step-by-step explanation:

since there's no equal sign or no value that it shows all of that added together is equivalent to it's not really equal to anything. However if you're asking what that equation would look like if you simplified it down , then it would be 3 + 3p because you combine the like terms

Lin counts 5 bacteria under a microscope. She counts them again each day for four days, and finds that the number of bacteria do
Liula [17]

Answer:

The population of bacteria can be expressed as a function of number of days.

Population = \[5*2^{n-1}\] where n is the number of days since the beginning.

Step-by-step explanation:

Number of bacteria on the first day=\[5 * 2^{0} = 5\]

Number of bacteria on the second day = \[5 * 2^{1} = 10\]

Number of bacteria on the third day = \[5*2^{2} = 20\]

Number of bacteria on the fourth day = \[5*2^{3} = 40\]

As we can see , the number of bacteria on any given day is a function of the number of days n.

This expression can be expressed generally as \[5*2^{n-1}\] where n is the number of days since the beginning.
