add using the number line.  1.4+(−0.8)  select the location  on the number line to plot the point.

Answer : The location on the number line to plot the point is shown below.

Step-by-step explanation :

Number line : It is defined as a straight line with the numbers that are placed at equal intervals along its length.

As we move from zero to the right the numbers are positive.

As we move from zero to the left the numbers are negative.

The given expression is:

1.4 + (-0.8)

By solving the expression, we get:

⇒ 1.4 - 0.8

⇒ 0.6

whats the

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
