Answer:
Given sum of interior angles = 1260. n = 13.
Step-by-step explanation:
Therefore the number of sides = 13.
Answer:
y - 8 = x + 7
Step-by-step explanation:
To write the equation of a line use the point slope form. Substitute m = 1 and (-7,8).

Y = 2x + 7.....the slope is 2 and the y int is 7
y = 1/2x + 7...the slope is 1/2 and the y int is 7
In comparison, the only difference is the slope. And if the original equation has a slope of 2, and it is changed to a slope of 1/2, then it will have a " less steep " slope. In other words, the slope will not be as steep....but the y intercepts will be the same.
