This is a right triangle, so first find the distance between the two legs...

Points where the numbers are the same indicate a point that is on the same axis as the other

(-3, 3) and (-3, 2) have a distance of 1


(-3,2) and (1,2) have a distance of 4

The area formula for a triangle is 1/2bh and in this case 1/2(1)(4) = 2

The area is 2

natural numbers will ____ be whole numbers. Integers will ___ be natural numbers. Irrational numbers will ___ be real numbers. R
NARA [144]

- Natural numbers will Always be whole numbers.

Natural numbers are positive integers (whole numbers), so, they are always whole numbers.

- Integers will Sometimes be natural numbers.

Not all integers are natural numbers. Negative integers are not natural numbers while positive integers are natural numbers.

- Irrational numbers will Always be real numbers.

Real numbers consist of both irrational and rational numbers. So, all irrational numbers are real numbers.

- Rational numbers will Never be irrational numbers.

Rational numbers and irrational numbers are two different types of real numbers.

- Rational numbers will Sometimes be integers.

Not all rational numbers are integers. there are some rational numbers that are not integers while some rational numbers are integers.

What is the equation of the line that passes through (4, -1) and (-2, 3)?
salantis [7]

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (4, - 1) and (x₂, y₂ ) = (- 2, 3)

m = \frac{3+1}{-2-4} = \frac{4}{-6} = - \frac{2}{3} , thus

y = - \frac{2}{3} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, 3) , then

3 = \frac{4}{3} + c ⇒ c = 3 - \frac{4}{3} = \frac{5}{3}

y = - \frac{2}{3} x + \frac{5}{3} ← in slope- intercept form

Multiply through by 3 to clear the fractions

3y = - 2x + 5 ( add 2x to both sides )

2x + 3y = 5 ( subtract 5 from both sides )

2x + 3y - 5 = 0 ← in general form
