Answer:
y = 2x + b (the second answer choice)
Step-by-step explanation:
The slope-intercept form is y = mx + b (the m representing slope and the b representing y-intercept). Put the points in ratio form as a fraction and subtract the ratio with the smallest numbers from the ratio with the largest ratio (5/1 - 1/-1) to get 4/2. When simplified, it becomes 2/1, so the slope is 2. Using the slope found previously, subtract 1 from the x of (1, 5) and 2 from the y of (1, 5) to get the y-intercept. The resulting point is (0, 3), so the y-intercept is 3. Replace the m with the found slope (2) and b with the found y-intercept (3) to end up with y = 2x + 3.

Answer:
2 1/4 inches
Step-by-step explanation:
1/4 per 1 foot so if there are 9 feet it would be 9/4 then converte that to a proper fraction which is 2 1/4
Answer:
Therefore the required relationship is
Step-by-step explanation:
Given that, to begin a bacteria study a petri dish had 2200 bacteria cells every hours.
The growth of bacteria is in exponential.So we use the following formula
A= Total amount =y = the number of bacteria cell
P= initial value = 2000
r= rate of increase = 3.8%= 0.038
n = time = t
Putting the all values
Therefore the required relationship is
