Answer:
Therefore the equation of the line has a slope 2 and passes through ( 10 , 17 ) is
2x - y = 3
Step-by-step explanation:
Given:
Slope = 2 = m ( say )
Let,
point A( x₁ , y₁) ≡ ( 10 , 17 )
To Find:
Equation of Line AB =?
Solution:
Equation of a line passing through a points A( x₁ , y₁) and having slope m is given by the formula,
Substituting the given values in a above equation we get
Therefore the equation of the line has a slope 2 and passes through ( 10 , 17 ) is
2x - y = 3
A scientist has collected the following data on the population of a bacteria colony over a thirty-minute period:
5 minutes: 78,000
10 minutes: 234,000
15 minutes: 657,000
20 minutes: 1,784,000
25 minutes: 5,040,000
30 minutes: 14,980,000
Which type of graph would be best to use to display the growth of the colony?
A.) a bar graph
B.) a circle graph
C.) a histogram
D.) a line graph
An bar graph suits the best in this type of study because we can easily understand the growth and decrease of that particular thing which is being studied.
