Step-by-step explanation:

B represents a union. All numbers between -2.5 and 2 satisfy two different requirements: x > -2.5 AND x < 2.

A represents an intersection x < -2.5 OR x > 2

Write an equation in standard form of the line that passes through the given points:

Dafna1 [17]

Step-by-step explanation:

The standard form for a line is Ax+By=C

First, we need to find the slope, or change in y over change in x. For the first one, this is

$\frac{6-(-2)}{2-2}$ , which is impossible to find as we cannot divide by 0, meaning that this is constant horizontally -- in this case, x=2. Thus, we have 1*x+0*y=2.

For the second one, we can find the slope by getting

$\frac{0-4}{3-(-3)} =\frac{-4}{6 } = \frac{-2}{3}$ . We can then take the point (3,0) (it can be any point on the line) and get our equation to be y-0 = (-2/3) (x-3). Converting this to standard form, we can expand this to get
