Answer:

  • (5, 2)

Step-by-step explanation:

<u>Given system:</u>

  • x + 2y = 9
  • x = 2y + 1

<u>Solve for y by substitution:</u>

  • (2y + 1) + 2y = 9
  • 4y + 1 = 9
  • 4y = 8
  • y = 2

<u>Find the value of x:</u>

  • x = 2*2 + 1
  • x = 5

Answer: y = 2

Step-by-step explanation:

we need to use systems of equations, basically since we know what x equals, we plug that into first equation so:

since x=2y+1,

we can say that:

(2y+1)+2y=9

then we solve this equation,

first we expand the brackets- 2y+1+2y=9,

then we combine like terms- 4y+1=9

then we take 1 away from both sides- 4y=8

then we divided both sides by 4

y=2

Hope this helps xx

3 = -2x + 1 what is the value of x
DerKrebs [107]

Subtract 1 from both sides

3 - 1 = -2x

Simplify 3 -1 to 2

2 = -2x

Divide both sides by -2

-1 = x

Switch sides

<u>x = -1</u>

Find a point-slope form for the line with slope 1/5 and passing through the point (- 4. - 8).
andrew11 [14]

Answer:

y+8 = 1/5(x+4)

Step-by-step explanation:

The point slope form of a line is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y- -8 = 1/5(x - -4)

y+8 = 1/5(x+4)

Find the slope of the line passing through the points (8,-3) and (4,-1)
docker41 [41]

\rm \to m =  \dfrac{y_2 - y_1}{x_2 - x_1}

\\  \\

\rm \to m =  \dfrac{ - 1 - 3}{4 - 8}

\\  \\

\rm \to m =  \dfrac{ - 4}{4 - 8}

\\  \\

\rm \to m =  \dfrac{ - 4}{ - 4}

\\  \\

\rm \to m = \cancel  \dfrac{ - 4}{ - 4}

\\  \\

\rm \to m = 1
