<u>Using a number line to show what -4 + 3 equals:</u>

Start at the -4.  Move three spaces to the right (+3).  You land on -1.


<u>Using a number line to show what 3 + (-4) equals:</u>

Start at the 3.  Move four spaces to the left (-4).  You land on -1.


The commutative property of addition states that a + b = b + a.

The scale of a map is 1:1,000,000. What are the real distances between two points if the distance between them on this map is 35
Inessa [10]

35km; Since the points on the map are one millionth of their actual size, simply multiply by one million and convert from there.

35*1,000,000 = 35,000,000mm

35,000,000/1000 = 35,000m

35,000/1000 = 35km

Cual es la ecuación de la recta que pasa por el punto (2;-1/2) y tiene de pendiente m=-2/3
timama [110]

Answer:

y = (-2/3)x + 5/6

Step-by-step explanation:

The general structure of a line in slope-intercept form is:

y = mx + b

In this form, "m" represents the slope and "b" represents the y-intercept. You have been given the value of "m". To find the value of "b", you can plug the slope and the values from the point (2, -1/2) into the general equation.

m = -2/3

Point (2, -1/2):

x = 2 and y = -1/2

y = mx + b                                  <----- Slope-intercept form

y = (-2/3)x + b                            <----- Insert -2/3 in "m"

-1/2 = (-2/3)(2) + b                      <----- Insert "x" and "y" values from point

-1/2 = -4/3 + b                            <----- Multiply -2/3 and 2

-3/6 = -8/6 + b                           <----- Give the fractions common denominators

5/6 = b                                      <----- Add 8/6 to both sides

Thus, the equation of the line is:

y = (-2/3)x + 5/6
