Answer:
Lorena made a mistake when she subtracted x1 from x2
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
In this problem we have
The points are and
therefore
She made a mistake when she subtracted x 1 from x 2.
<em>y = - </em><em> x </em>
1). = +
= +
⊥ if = -
2). ( , )
y - = m( x - )
~~~~~~~~~~~~~~~~~~
y = x + 7
=
= -
( 3, - 4 )
y - ( - 4) = - ( x - 3 )
y + 4 = - x + 4
Repeat step 1 for BC or AC
