Answer:
In geometry, an angle of a polygon is formed by two sides of the polygon that share an endpoint. For a simple (non-self-intersecting) polygon, regardless of whether it is convex or non-convex, this angle is called an interior angle (or internal angle) if a point within the angle is in the interior of the polygon. A polygon has exactly one internal angle per vertex.
If every internal angle of a simple polygon is less than 180°, the polygon is called convex.
In contrast, an exterior angle (or external angle) is an angle formed by one side of a simple polygon and a line extended from an adjacent side.
Step-by-step explanation:
Slope shows both steepness and direction. With positive slope the line moves upward when going from left to right. With negative slope the line moves down when going from left to right. If two linear functions have the same slope they are parallel.

Step-by-step explanation:
The capacity of the washing machine is gallons.
She uses gram soap for ![\[10\]](https://tex.z-dn.net/?f=%5C%5B10%5C%5D)
gallon of water
Her son by mistake dissolved ![\[60\]](https://tex.z-dn.net/?f=%5C%5B60%5C%5D)
grams of soap to gallons of water.
![\[60\]-](https://tex.z-dn.net/?f=%5C%5B60%5C%5D-)
gram soap is right for ![\[30\]](https://tex.z-dn.net/?f=%5C%5B30%5C%5D)
gallons of water, thus gallon of water must be added more.
She pore water ![\[2\]](https://tex.z-dn.net/?f=%5C%5B2%5C%5D)
gallons per minute thus, gallons of water will takeminutes.

Answer:
point-slope form:
y - 10 = -4(x - -2)
y - 10 = -4(x + 2)
---
slope-intercept form:
y - 10 = -4x - 8
y = -4x - 8 + 10
y = -4x + 2
