What is the slope of the line that passes through the points (4, 7) and (8, 9)

SSSSS [86.1K]

Answer:

y = 0.5x + 5

Step-by-step explanation:

Use the slope formula to find the slope of a line given the coordinates of two points on the line.

The slope formula is:

m = $\frac{y{2}-y{1} }{x{2}- x{1} }$ = $\frac{y}{x}$

The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

Now let's fill in the formula with the points,

m = $\frac{8-4}{9-7}$

Solve,

⇒ Y = 9 – 7 = 2

⇒ X = 8 – 4 = 4

m = $\frac{8-4}{9-7}$ = $\frac{2}{4}$

Simplify,

⇒ $\frac{2}{4}=\frac{1}{2}=0.5$

Therefore, the Equation of the line is y = 0.5x + 5.

Is it possible for a composite number to have more than one prime factorization? Is it possible for a number to have no prime fa

Nitella [24]

Prime factors are factors of a composite number that are indivisible except by the number 1 or the number itself. The answers to your questions are the following:

1. Yes, it is possible especially for very large numbers.
2&3. No, because as mentioned previously, the default prime factors of numbers are 1 and the number itself. For example, 2 is a prime number. Its factors are 1 and 2.
4. Prime factorization are useful in fields of encryption. They make use of the basic prime numbers for the arithmetic modulus with the general equation: n=pq.
