Answer:
If you can draw one straight line through a polygon and cross more than two sides, the polygon is concave - A.
Answer:
The equation of the line is y - 12 = (x + 9) ⇒ B
Step-by-step explanation:
The slope-point form of the linear equation is
y - y1 = m(x - x1), where
- m is the slope of the line
- (x1, y1) are the coordinates of a point lie on the line
∵ The slope of a line is
∴ m =
∵ The line passes through point (-9, 12)
∴ x1 = -9 and y1 = 12
→ Substitute these values in the form of the equation above
∵ y - 12 = (x - -9)
→ Remember (-)(-) = (+)
∴ y - 12 = (x + 9)
∴ The equation of the line is y - 12 = (x + 9)
