Write an equation of the line that is perpendicular to 3x + 9y = 7 and passes through the point (6, 4).
musickatia [10]
Hi there!

The equation of any line perpendicular to
ax + by = c
is
bx - ay = c

Therefore, in this situation, the formula of the line would be
9x - 3y = c

Given that the line passes through the point (6, 4) we get
9 \times 6 - 3 \times 4 = c
54 - 12 = c
c = 44

Therefore, the equation of the line that is perpendicular to 3x + 9y = 7 and passes through (6, 4) is
9x - 3y = 44

An angle measures 152° less than the measure of its supplementary angle. What is the measure of each angle?
GrogVix [38]

Two supplementary angles when added together need to equal 180 degrees.

Let the first angle = X

The second angle would then be X - 152

Add them together to equal 180:

X + X - 152 = 180

Simplify:

2X -152 = 180

Add 152 to each side:

2X = 332

Divide both sides by 2:

X = 332 / 2

X = 166

The first angle = X = 166 degrees.

The second angle = X - 152 = 166 - 152 = 14 degrees.

The angles are 166 and 14

What is the slope?? Hdhdhfucufuchchdbdbdvrvrvdbshshd
Anuta_ua [19.1K]

Answer:

-2/3

Step-by-step explanation:

To find the slope, pick two points on the line, and use the slope formula

( 0,50) and  (30,30)

m = ( y2-y1)/(x2-x1)

   = (30-50)/(30-0)

    = -20/30

   = -2/3
