Slope of the line
(6-1) / (-5-0)
5 / -5
-1
General equation of the line
y = -x + c
if this passes through (0,1)
0 = (-1*1) + c
c = 1
so the equation is
y = -x + 1
To find the measure of an interior angle of any regular polygon, we use the formula:
180 * (n-2) / n,
where n is the number of sides in the regular polygon.
Therefore, if there are 15 sides in the regular polygon, your answer would be
180 * (15-2) / 15,
or when simplified,
180 * 13 / 15
2340 / 15
156 degrees.
Thus, the measure of an interior angle of a regular polygon with 15 sides is 156 degrees.

Answer:
a = (15-11b)/7
Step-by-step explanation:
19a + 11b = 12a + 15
Subtract 12a from each side
19a-12a + 11b = 12a-12a + 15
7a +11b = 15
Subtract 11b from each side
7a+11b-11b = 15 -11b
7a = 15-11b
Divide by 7
7a/7 = (15-11b)/7
a = (15-11b)/7
