A line with the slope of -4 passes through the point (8,-3). What is the equation in point slope form

1 answer:

8 0

Y=Mx + c
The slope is given already so it will be :
Y=-4x+c
Now you can find C by replacing the given points

-3=-4(8)+c

C=9

Final answer is :

Y= -4x+9

Find the midsegment of triangle ABC so that it is parallel to side BC and label it as segment EG on the graph coordinate of E: _

Sholpan [36]

Answer:

Coordinate of E: (-2,3) Coordinate of G: (2.5, 1.5)

Step-by-step explanation:

You first have to find the midpoints of AC and AB.

AC X coordinate:

X1+X2/2

Substitute the x points of AC in

1+(-5)/2=-2

AC Y coordinate:

Y1+Y2/2=3

Substitute the y points of AC in

5+1/2=3

You do the same thing with the AB line. I am pretty sure this works and I hope this helps!

How can I solve this proof?? PLZ HELP I DONT UNDERSTAND!! Thanks !!

love history [14]

Hello from MrBillDoesMath!

Answer:

See below

Discussion:

Triangles BAD and BCD are congruent by the SAS postulate.

* Side AD = DC because BD is the perpendicular bisector of AC.

* Angle ADB and CDB are both right angles, and hence equal, because

BD is the perpendicular bisector of AC)

Corresponding parts of congruent triangles are equal so angle BAD = angle BCD, which was to be proven.

Regards,

Which logarithmic equation is equivalent to the exponential equation below? E^a=60

Gala2k [10]

Answer:

Step-by-step explanation:

e is the base of the natural log system.

take the natural log of both sides.

ln(e^a) = ln(60) The power can come down

a ln(e) = ln(60) The natural log of e = 1

a * 1 = ln (60)

a = ln(60)

What is the equation for the line of reflection? On a coordinate plane, triangle A B C has points (6, 3.7), (5.4, 2), (1, 3). Tr

elixir [45]

Answer:

The equation for the line of reflection will be x = y.

Step-by-step explanation:

On a coordinate plane, triangle Δ ABC has points (6, 3.7), (5.4, 2), (1, 3). Triangle Δ A'B'C' has points (3.7, 6), (2, 5.4), (3, 1).

And we have to find the equation of the line of reflection of the points.

Now, it is clear from the coordinates of vertices of Δ ABC and Δ A'B'C' that after reflection the x and y-values of the respective coordinates interchange and there is no change in signs.

Therefore, the equation for the line of reflection will be x = y. (Answer)
