Answer:
y = 1/3x +6
Step-by-step explanation:
The slope of the given line is the coefficient of x, -3. The slope of the perpendicular line will be the opposite reciprocal of that:
-1/(-3) = 1/3
The point-slope equation is then ...
y -k = m(x -h) . . . . . for line of slope m through point (h, k)
Here, we have m = 1/3, (h, k) = (-3, 5), so the point-slope equation is ...
y -5 = 1/3(x +3)
y = 1/3x + 1 + 5 . . . . eliminate parentheses, add 5
y = 1/3x +6 . . . . slope-intercept equation of the line
Answer:
i am not sure but tried .

Step-by-step explanation:
Since there are as many of these triangles as the polygon has sides (eight for an octagon), you have to multiply the area of this triangle by the number of sides. You will obtain the total area of the octagon: area of octagon = 8 * base * height / 2 = perimeter * apothem / 2 .
i hope this helped you :)
