Answer:
y = 5x + 2
Step-by-step explanation:
Standard form of Equation of line: y = mx + c
where m = slope or gradient,
c = y-intercept
From the question we know that:
x = - 1
y = - 3
m = 5
We will substitute these values into the equation to find c.
- 3 = (5)(- 1) + c
- 3 = - 5 + c
c = - 3 + 5 = 2
Therefore the equation of this line is: y = 5x + 2
Let's go through this term by term.
- Rational number- a number that can be expressed as a fraction.
Since -6 is obviously not a fraction, it is not a rational number.
- Irrational number- a number that cannot be expressed as a fraction- has an infinite amount of numbers when written as a decimal.
Again, -6 isn't infinite nor is it a decimal or fraction- that's out of the way.
- Whole number- a number; an integer.
An integer (or whole number) includes positive and negative numbers- so -6 is a whole number and an integer! You can put either though, since they are both the same.
- Real numbers- numbers that are either algebraic or transcendental, rational or irrational, or positive, negative, or 0.
Since -6 is a negative number, it is a real number as well.
Answer: Whole number, integer, and real number

Step-by-step explanation:
Convert to a decimal by dividing the numerator by the denominator.
When the velocity goes from 40km/h to 20 km/h, the kinetic energy decreases by a factor of 4.
<h3>
What happens to the kinetic energy?</h3>
We know that the kinetic energy depends of the square of the velocity. Thus, if we decrease the velocity from 40km/h to 20km/h, then the kinetic energy decreases.
Remember that the kinetic energy is:
K = (m/2)*v²
Where m is the mass.
The initial kinetic energy is:
K = (m/2)*(40km/h)²
The final kinetic energy is:
K' = (m/2)*(20km/h)²
The quotient gives:
K/K' = [ (m/2)*(40km/h)²]/[ (m/2)*(20km/h)²]
K/K' = (40km/h)²/(20km/h)² = 4
So the kinetic energy decreases by a factor of 4.
