Answer:
<u><em>1.) 20.2</em></u>
Step-by-step explanation:
1.) You need to use the distance formula:
Find the distance of A to B first:
B to C:
C to A:
Add distances to find the perimeter:
2.) Part A:
You need to use the mid-point formula:
Part B:
1. Use the slope-intercept formula:
M as the slope, b the y-intercept.
Find the slope of the two points A and B using the slope formula:
Insert slope as m into equation.
Take point A as coordinates and insert into the equation. Solve for the intercept, b:
Insert the value of b into the equation.
2. Use the mid-point coordinate. Take the slope.
If you need to find the perpendicular bisector, you will take the negative reciprocal of the slope. Switch the sign and flip it. Ex:
Insert the new slope into the slope-intercept equation as m.
Take the mid-point coordinate as (x,y) and insert into the equation with the new points. Solve for b.
Insert the value of b.
Answer:
Step-by-step explanation:
Slope intercept form: y = mx + b
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (-5 - (-4)) / (0 - 4)
= -1 / -4
= 1/4
Find y intercept using anyone of the given points and slope from above:
y = mx + b
b = -5
Now use the above slope and y intercept to create equation of a line:
