Answer:
y-intercept: (0,3)
x-intercept: (-6,0)
Step-by-step explanation:
put equation into y=mx+b
-x+2y=6 (add x to both sides)
2y=6+x (divide both sides by 2)
y=.5x+3
find y-intercept
set x=0
solve for y, y=3
y-intercept (0,3)
find x-intercept
set y=0
solve for x, x=-6
x-intercept (-6,0)

Answer:
15 cm
Step-by-step explanation:
The area of an equilateral triangle is:
, where a is the length of one side.
We can find the value of a (the length) by:
a = 5, so the side length of this triangle is 5 cm.
The perimeter of an equilateral triangle will be 3 times the length.
Hope this helped!
