Based on the definition of an angle bisector, there is an erro in line 1, because, BC is an angle bisector.

<h3>What is an Angle Bisector?</h3>

An angle bisector is a line segment that bisects an angle into congruent parts.

In the proof given, since C is the incenter of the isoscles triangle ABD, therefore, line segment BC bisects ∠ABD.

This implies that BC is an angle bisector of ∠ABD not altitude.

Therefore, based on the definition of an angle bisector, there is an erro in line 1, because, BC is an angle bisector.

Write an equation in standard form of the line passing through the points (12, 3) and (-3, 8).

aliya0001 [1]

Answer:

x + 3y = 21

Step-by-step explanation:

$(x_{1},y_{1})=(12,3) \\\\(x_{2},y_{2})=(-3,8)\\\\Slope= \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\= \dfrac{8-3}{-3-12}= \dfrac{5}{-15}\\\\= \dfrac{-1}{3}$

Equation of the line: y =mx+ b

$y = \dfrac{-1}{3}x+b\\\\\\Plugin \ x = 12 \ and \ y=3 \ in \ the \ above \ equation\\\\3= \dfrac{-1}{3}*12+b\\\\3= -4+b\\\\3+4 = b\\\\b = 7\\\\\\\y= \dfrac{-1}{3}x+7\\\\$

Multiply the equation by 3

3y = -x + 21

x + 3y = 21

-9x - 33 + 17 - 19x simplify

labwork [276]

Answer:

-28x -16 is the simplified answer.

Step-by-step explanation:

You have to move your constants towards your constants. So -9x and -19x are constants because their variable is the same. SO -9x plus -19x is -28x. And -33 and 17 are constant because they have the same variable so -33 plus 17 is -16. You can recheck my math to make sure.
