sophia is designig a logo with three lines,y, m, and n. Line m passes through point (-2, -1) and is perpendicular to the graoh of y=-2/3 x +6. line n is parallel to line m and passes through the point (4, -3). what is the equation in slope-intercept form of linen?

Respuesta :

Answer:

y = 3/2x - 9

Step-by-step explanation:

Finding equation of line m

  • ⊥ to the line y = -2/3x + 6
  • new slope = -(-3/2) = 3/2
  • Passes through the point (-2, -1)
  • y + 1 = 3/2(x + 2)
  • y + 1 = 3/2x + 3
  • y = 3/2x + 2

Equation of line n

  • Parallel ⇒ slope is same = 3/2
  • Passes through the point (4, -3)
  • y + 3 = 3/2(x - 4)
  • y + 3 = 3/2x - 6
  • y = 3/2x - 9

Answer:

[tex]\textsf{Equation of line n}:\quad y=\dfrac32x-9[/tex]

Step-by-step explanation:

Equation of line m

If two lines are perpendicular to each other, the product of their slopes will be -1.

The slope of the line [tex]y=-\dfrac23x+6[/tex] is [tex]-\dfrac23[/tex]

Therefore, the slope of the line m is:

[tex]\implies m \times -\dfrac23=-1[/tex]

[tex]\implies m=\dfrac32[/tex]

If line m passes through point (-2, -1), then the equation of line m is:

[tex]\implies y-(-1)=\dfrac32(x-(-2))[/tex]

[tex]\implies y+1=\dfrac32(x+2)[/tex]

[tex]\implies y=\dfrac32x+2[/tex]

Equation of line n

If line n is parallel to line m, then they will have the same slope.

Therefore, slope of line n is [tex]\frac32[/tex]

If line n passes through point (4, -3), then the equation of line n is:

[tex]\implies y-(-3)=\dfrac32(x-4)[/tex]

[tex]\implies y+3=\dfrac32x-6[/tex]

[tex]\implies y=\dfrac32x-9[/tex]
