Create an equation in slope intercept form given a point and a slope or given two points (-4,-7) and slope =3

So we need to start by using point slope form.

The general forumla of point slope is:

Y₁ Is the Y Coordinate, X₁ is the X Coordinate, and M is the slope. So we plug these numbers into our formula.  

Now, In order to solve in slope-intercept form, we have to isloate the Y and make sure it follows Y = mx+b so.  

So the equation is Y = 3x+5

linearly: 8560 bacteria

exponentially: approximately 75233 bacteria

step-by-step explanation:

assuming it is not exponential (we would have some really complicated logarithms), let's say it is linear. then, after 5 hours, it increased by 1200 bacteria, so every hour it increases by 240 bacteria. this means that after 19 hours, we get 19 * 240 + 4000 bacteria or 3800 + 760 + 4000 = 7800 + 760 = 8560 bacteria.

because it says round your answer, i will do this exponentially (with a calculator, of course). first, we need to find how much it multiplies by every hour, by taking the 5th root of 52/40 or 13/10. this is approximately 0.167. we still need to add 1 to this, because we are multiplying by that number, not adding that amount of the number. now, we just calculate 4000 * (1.167)^19. use a calculator to get approximately 75232.6, or 75233.
