Answer:
y = 4x - 9
Step-by-step explanation:
Use the formula:
y = mx + b
Where m is the slope, b is the y-intercept.
The slope is 4.
y = 4x + b
The y-intercept is -9 because it passes through (0, -9).
y = 4x - 9
Answer:
180°
Step-by-step explanation:
The sum of the exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle in a regular polygon is: 360 number of sides. If you know the exterior angle you can find the interior angle using the formula: interior angle + exterior angle = 180°
