What is an equation of the line that is perpendicular to y=−3/4x+6 and passes through the point (3, 9) ?
Arisa [49]

Answer:

y=4/3x+5

Step-by-step explanation:

Perpendicular means the slope will be the negative reciprocal.

So the slope=4/3

y=4/3x+b

Now, enter the point (3,9) into the equation.

9=4/3(3)+b

9=4+b

b=9-4

b=5

P(-3,-5) and Q(1, -3) represent points in a coordinate<br> plane. Find the midpoint of PQ.
Karolina [17]

Step by step explanation :

The two points are ,

  • P( -3 , -5)
  • Q (1 , -3)

We can find the midpoint by finding the median of x coordinate and y coordinate .

\tt\to Midpoint = \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\tt\to Midpoint =\bigg(\dfrac{-3+1}{2},\dfrac{-5-3}{2}\bigg)\\\\\tt\to Midpoint = \bigg( \dfrac{-2}{2},\dfrac{-8}{2}\bigg) \\\\\sf\to\boxed{\orange{\tt Midpoint = (-1,-4)}}
