Which of the following ordered pairs is a possible solution to the equation y = -2/3x - 4
Karolina [17]

The ordered pair that is the possible solution for the equation is (-6,0) (0,-4).

<h3>What is the Slope-intercept form of a linear equation?</h3>

The slope-intercept form of a linear equation takes the form y= mx + b.

Here:

  • Slope = m
  • b = y-intercept

The function f(x) = y = \mathbf{-\dfrac{2}{3}x-4}

\mathbf{y = -\dfrac{2}{3}x-4}

The slope (m) = -2/3

The x-intercept is the value of x for which y = 0

  • x-intercept = (-6,0)

The y-intercept is the value of y for which x = 0

  • y-intercept = (0,-4)

The value of x is:<br> xo<br> 20°<br> 300<br> 20°<br> 30°.<br> 0000<br> 50°.<br> 60°
AysviL [449]

Answer:

x = 50°

Step-by-step explanation:

x + 20° + 30° = 180°

x = 180° - 20° - 30°

x = 130°                   (This one is other x)

x + 130° = 180°

x = 180° - 130°

x = 50°
