A triangle is isosceles is the altitude from the vertex angle to the base also passes through the midpoint of the base. What are the two slopes from the figure that prove this? M is the midpoint of triangle ABC.

-7 and 1/7

5 and -1/5

-5 and 1/5

7 and -1/7

The answer to your question is  7 and -1/7

Step-by-step explanation:

Data

First line                        Second line

B (4, 4)                            A (0, 1)

M (3.5, 0.5)                     C (7, 0)

Formula

Slope = m = (y2 - y1) / (x2 - x1)

Process

1.- Calculate the slope of the first-line

    x1 = 4        y1 = 4

    x2 = 3.5    y2 = 0.5

-Substitution

    m = (0.5 - 4) / (3.5 - 4)

-Simplification

     m = -3.5 / -0.5

-Result

     m = 7

2.- Calculate the slope of the second line

    x1 = 0          y1 = 1

    x2 = 7         y2 = 0

-Substitution

   m = (0 - 1) / (7 - 0)

-Simplification

   m = -1/7

-Result

   m = -1/7  

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
