Answer:y=-2x-1


Step-by-step explanation:

(1,-3) and a slope of -2

Use Formula

Y= mx +b to find b. By using the slope and point given .

M is slope

Y is -3

X Is 1



Y=mx+b


-3= -2(1)+b


-3= -2+b


-3+2=b


-1=b


Now create the equation by inputting the slope they gave you which is -2 and answer we solved for b which is -1 .


Y= -2x-1

How do i find the shorted distance between the point and the line
m_a_m_a [10]

Answer:

5 units

Step-by-step explanation:

3x + 4y = 8

4y = -3x+8

y = -3/4+2

The shortest distance between a point and a line is the perpendicular line.

Slope of the perpendicular line: 4/3 and point (-3,-2)

b = -2-(4/3)(-3) = 2

Equation of the perpendicular line: y=4/3x+2

y is equal y

4/3x+2= -3/4x+2

4/3x +3/4x = 2-2

x = 0

Plug x=0 into one of the equations to find y

y = 4/3(0) + 2

y = 2

(0,2) and (-3,-2)

Distance = sqrt [(-3-0)^2 + (-2-2)^2]

Sqrt (-3)^2+ (-4)^2

Sqrt 25 = 5

26. Given the point A(-2,4) translate (x,y) → (x – 4, y - 3) and then reflect over the line y = -x.
Zepler [3.9K]

<em>Greetings from Brasil...</em>

Here is the graphical explanation in the annex.

A = (-2; 4)

A' = (-2 - 4; 4 - 2) = (-6; 1)

After reflection on F(X)

<h2>A'' = (-1; 6)  </h2>
