Write in standard form an equation for the line with slope 1/3 through<br> the point (2,-2).

Alexxandr [17]

Answer:

x - 3y = 8.

Step-by-step explanation:

Use the point-slope form of the equation of a line:

y - y1 = m(x - x1) where m = the slope and (x1, y1) is a point on the line.

So substituting the given values:

y - (-2) = 1/3(x - 2)

y + 2 = 1/3x - 2/3 Multiply through by 3:

3y + 6 = x - 2

x - 3y = 6 + 2

x - 3y = 8 <---- Standard Form.

The figure is made up of a square and a rectangle. Find the area of the shaded region.

inn [45]

Answer:

$10 \: { \: m}^{2}$

Step-by-step explanation:

area of the shaded region = Area of triangle formed in rectangle with base (10 - 6 = 4) 4m and height 2 m + Area of triangle formed in square with base 2 m and height 6 m

$= \frac{1}{2} \times 4 \times 2 +\frac{1}{2} \times 2\times 6 \\ \\ = 4+6 \\ \\ = 10 \: { \: m}^{2}$
