    Sum if the inner angles of the quadrilateral:
    150° + 90° + 90° + x = 360°
    330° + x = 360°
    x = 360° - 330°
    x = 30 °

A Point-Slope equation of a straight line has this form: y - y1 = m(x-x1)

We can recognize any points of the graph.
(0,80000) ; (10,50000)

Given:
<span>y -50,000 =______(x -10)

We need to find the slope.

Slope = Change in y / Change in x = 80,000 - 50,000 / 0 - 10 = 30,000 / -10 = -3,000

The slope is equal to -3000. Choice A.

</span><span>y -50,000 = -3,000(x -10)</span>

Misha Larkins [42]

Answer:

8

Step-by-step explanation:

The equation is of the form

y = kx ← k is the constant of proportionality

To find k use the slope formula

k = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (2, 16) ← 2 points on the line

k = \frac{16-0}{2-0} = \frac{16}{2} = 8
