Answer:

Step-by-step explanation:

Area of polygon = area of square + area of triangle

Square:

Side = 12 cm

Area of square = side *side

= 12 * 12

= 144 sq.cm

Triangle:

base (b) = 12 cm

Height h = 19 cm

$Area =\frac{1}{2}bh\\\\=\frac{1}{2}*12*19\\$

= 6 * 19

= 114 sq.cm

Area of polygon = 144 + 114 = 258 square cm

The Slope of a Line

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

The graph provided suggests the use of the points (3,-3) and (5,-3). The slope is:

$\displaystyle m=\frac{-3+3}{5-3}=\frac{0}{2}=0$

The slope of the line is 0. It corresponds to a horizontal line
