Write a linear equation. Explain it in number please! 20 points!!!
juin [17]

To find a linear question, we must have two points on the line and we must know the slope.

Let us choose two points at random:

    (-6,12)    and    (-5,14)

Now let us find the slope of the linear line:

 m = \frac{y2-y1}{x2-x1} =\frac{14-12}{-5--6}  = 2

   So the slope is 2.

Now let us set up the equation which now requires only one point and the slope

      let us use the point (-6,12) and the slope of 2

      y-12 = 2(x+6)\\y = 2x +12 +12\\y= 2x +4

So the linear line is y = 2x + 4.

Hope that helps!

Solve the inequality for V.<br><br> -8.3 _&gt;_ V - 1.9
Arada [10]
First keep in mind that the given value is negative and that it is greater than or equal to whatever '<em>v</em>' is.

-8.3  \geq v - 1.9

When solving for a variable in any equation, you do something to both sides in order to keep it equal. Here, <em>v</em> is being subtracted by 1.9; therefore we can add 1.9 to both sides in order to isolate <em />the variable.

-8.3 + 1.9  \geq v - 1.9 + 1.9
-6.4 \geq v

Despite not needing a value for the question, it is worth noting that since this is an inequality, <em>v </em>can be any value from -6.4 to ∞ in order to make it true.
