Which statement best explains the relationship between
Nataly [62]

Answer:

The best statement which explains the relationship between lines AB and CD is "They are parallel because their slopes are equal" ⇒ A

Step-by-step explanation:

  • Parallel lines have equal slopes and different y-intercepts
  • The rule of the slope of a line passes through points (x1, y1) and (x2, y2) is m = \frac{y2-y1}{x2-x1}

In the given figure

∵ The blue line passes through points A and B

∵ A = (-4, -2) and B = (4, 4)

∴ x1 = -4 and y1 = -2

∴ x2 = 4 and y2 = 4

→ Substitute them in the rule of the slope

∵ m(AB) = \frac{4--2}{4--4} = \frac{4+2}{4+4} = \frac{6}{8} = \frac{3}{4}

∴ The slope of line AB is  \frac{3}{4}

∵ The green line passes through points C and D

∵ C = (0, -3) and D = (4, 0)

∴ x1 = 0 and y1 = -3

∴ x2 = 4 and y2 = 0

→ Substitute them in the rule of the slope

∵ m(CD) = \frac{0--3}{4-0} = \frac{0+3}{4} = \frac{3}{4}

∴ The slope of line CD is  \frac{3}{4}

∵ The slope of line AB = the slope of line CD

∵ Parallel lines have the same slope

∴ AB // CD

∴ AB and CD are parallel lines

The best statement which explains the relationship between lines AB and CD is "They are parallel because their slopes are equal"

Answer:

56

Step-by-step explanation:

A fraction consists of two numbers and a fraction bar:

14/25

The number above the bar is the numerator: 14

The number below the bar is the denominator: 25

Divide the numerator by the denominator to get fraction's value:

Val = 14 ÷ 25
