Answer:

B

Step-by-step explanation:

Because you add -4 and 6 together to get a numerator of 2, then you keep the same denominator,7, to get 2/7.

Passes through (6 1) and is perpendicular to the line 3x-4y=2 standard form
Snowcat [4.5K]

Answer:

1⅓x + y = 9

Step-by-step explanation:

Convert the Standard Form of the given line to Slope-Intercept Form:

  1. -4y = -3x + 2 [Move -3x to the right side of the equivalence symbol]
  2. y = ¾x - ½ [Divide everything by -4]

Then, after getting your equation, take the OPPOSITE MULTIPLICATIVE INVERSE of ¾ [perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE <em>Rate</em><em> </em><em>of</em><em> </em><em>Changes</em><em> </em>(<em>SLOPES</em>)], which is -1⅓ [or -4⁄3]. After getting your slope, you can perform the action with your given ordered pair to find your y-intercept:

1 = -1⅓[6] + b

-8

9 = b

Now that you have your y-intercept, this is your new equation in <em>Slope-Intercept Form</em>:

y = -1⅓x + 9

We are not done just yet. The final step is to convert the Slope-Intercept Form of the line to Standard Form, and here is how it is done:

y = -1⅓x + 9

+1⅓x +1⅓x

--------------

1⅓x + y = 9 → Final equation
