Hi there! The slope formula is:

We know that the slope is 4 but we are missing the value of p. (Define m = slope)

What we have now are:

We are going to substitute these values and solve the equation for p-term.

Hence, the value of p is -10.

Next, we have to write the equation of a line in point-slope form. The point-slope form is:

Define that (x1, y1) = ordered pairs

Since we have two given points, we can either use the first point or second point. Both work.

First Point

For our first ordered pairs (4,2), substitute x1 = 4 and y1 = 2 in the equation.

Hence, the equation of a line in point-slope form as in (4,2) is y-2=4(x-4)

Second Point

For our second ordered pairs (1,p), we know that p = -10 from the equation that we solved. Therefore (1,p) = (1,-10). Substitute x1 = 1 and y1 = -10 in the equation.

Hence, the equation of a line in point-slope form as in (1,-10) is y+10 = 4(x-1)

Answer

Both equations work for point-slope form.

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
