Anton [14]

Answer: Y= -3/4x+13


Step-by-step explanation:

A line passes through the point (8,7) and has a slope of negative 3/4 Write an equation in slope-intercept form for this line.

This is what i get

Slope of a line Y= mx+b

Y= 7

X= 8

M= -3/4


7= -3/4(8)+b

7= -6+b

7+6=b

13=b


Y= -3/4x+13

State what additional information is required in order to know that the triangles are congruent by AAS. part 2
SVEN [57.7K]

Answer:

Step-by-step explanation:

The trick is to find the third angle

180 - A - <BCA = <CBA

180 - X - <BCX = <CBX

Everything else is OK

<CBA = <CBX                  Equals equated to an equal express = an equal expression.

Now by a little slight of hand, you get the two triangles to be equal by ASA, which always works.

Cheating you say? There is no such thing as cheating if it correct and it works.
