Find an equation perpendicular to x=1 and passing through (8,-9)
valina [46]

Answer:

y=-9

Step-by-step explanation:

We want to find an equation of a line that's perpendicular to x=1 that also passes through the point (8,-9).

Note that x=1 is a <em>vertical line </em>since x is 1 no matter what y is.

This means that if our new line is perpendicular to the old, then it must be a <em>horizontal line</em>.

So, since we have a horizontal line, then our equation must be our y-value of our point.

Our y-coordinate of our point (8,-9) is -9.

Therefore, our equation is:

y=-9

And this is in standard form.

And we're done!

JK is formed by J(-12,3) and K(8,-5). If line r is the perpendicular bisector of JK, write an equation for r in slope-intercept
dem82 [27]

Answer:

  • y = 5/2x + 4

Step-by-step explanation:

<u>Midpoint of JK:</u>

  • x = (-12 + 8)/2 = -4/2 = -2
  • y = (3 - 5)/2 = -2/2 = -1

<u>Slope of the line JK:</u>

  • m = (-5 - 3)/(8 - (-12)) = -8/20 = -2/5

Perpendicular lines have negative reciprocal slopes.

So the line r has a slope 5/2 and passes through the point (-2, -1)

<u>Equation of r:</u>

  • y = 5/2x + b
  • -1 = 5/2(-2) + b
  • -1 = -5 + b
  • b = 5 - 1
  • b = 4

<u>So the equation is:</u>

  • y = 5/2x + 4
