The formula of a distance between two points:
We have the points (-1, 8) and (5, -2). Substitute:
angle <1 ≅ <2 because vertical angles are congruent, CD ≅ BD because a midpoint divides a line segment into two congruent segments.
Step-by-step explanation:
1. Mark the angles formed by the bisecting lines with a "(" and ")" and label both with the numbers 1 and two for each angle to show that there are two angles and that they are congruent to eachother.
___
1. put vertical lines through the middle of CD and DB to indicate they are both congruent.
Answer:
Step-by-step explanation:
Slope intercept form :
y = mx + b
m is the slope
b is the y-intercept
Let's look for m, use the formula to determine it.
Now find b, we simply need to plug in one of our coordinates to get our answer.
(12, -9)
Solve for b :
-9 = -6 + b
-3 = b
b = -3
Our slope intercept is :
If your solving for for y, then simplify both sides of the equation, then isolating the variable.
y = 20
