What is the slope of the line passing through the points (2, 5) and (0, −4)?
Alexus [3.1K]
Plug the two points into the slope formula.

m = y2-y1/x2-x1

m = (-4 - 5)/(0 - 2)

m = -9/-2

m = 4.5

So the slope is 4.5

Which statement is true?
valentinak56 [21]

Answer:

  |-3| = 3 and -|-4| = -4

Step-by-step explanation:

The absolute value function changes the sign to positive, if it isn't already. The usual rules of arithmetic and logic apply to these statements.

|-3| = 3 (true) and -|-4| = -4 (true)   ⇒ this statement is true

|-3| = 3 (true) and |-4| = -4 (false)   ⇒ this statement is false

-|3| = 3 (false) and |4| = 4 (true)   ⇒ this statement is false

|-3| = 3 (true) and -|4| = 4 (false)   ⇒ this statement is false

<em>Additional comment</em>

A compound "and" statement is only true if <u>all</u> of the parts of it are true.
