Answer:
<em>The perimeter is 72 units and the area is 149 square units.</em>
Step-by-step explanation:
has coordinates
and
Using the distance formula.........
Length of side
Length of side
Length of side
So, the perimeter of the triangle will be: units. <em>(Rounded to the nearest unit)</em>
The height of the triangle for the corresponding base is 8.89 units.
<u>Formula for the Area of triangle</u>,
So, the area of the will be:
square units. <em>(Rounded to the nearest unit)</em>
Solve each equation for y and then the slope is m and y-intercept is b as in:
So, if you do that, you'll get (remember, this is <em>after</em> solving for y):
1. m = -6, b = -2
2. m = 5, b = -1
3. m = -5/3, b = 5
4. m = 0, b = -1/4
5. m = -1, b = -3
6. m = 3, b = -4
7. m = 1/2, b = -5/2
8. m = 7/2, b = 1
Hope this helps.
