What is the equation of the line that is perpendicular to y=2/3x-5 and passes through (6,-1)?
riadik2000 [5.3K]

Answer: 2y + 3x - 16 = 0

Step-by-step explanation:

Equation of the line  is    y = 2x/3 - 5

From the equation , the slope m₁ = 2/3. therefore recall, from condition for perpendicularity, m₁m₂ = -1

The product of their gradient must be (-1).

Now since m₁ = 2/3 and m₁m₂ =-1

                          2m₂/3 = -1

Therefore , m₂ = -3/2.

Since the equation passes through the coordinate of (6,-1)

we now substitute for x and y in the equation of a line to get the y intercept (c)

  y = mx + c

  -1 = -3x/2 +c

  -1 = -3/2 x 6 + c

  -1 = -9 + c

  -1 + 9 = c

 Therefore c = 8

Now to get the equation of line that is perpendicular to y = 2x/3 - 5

 y = -3x/2 + 8

making it a linear equation,

 2y = -3x + 16

 2y +3x - 16 = 0

Help please I need the name of the polygon and the perimeter and area of the shape of numbers 42-47
sergij07 [2.7K]

42 - 47

Polygons are

triangle, trapezoid, triangle, parallelogram, rectangle and parallelogram

The area of triangles = 1/2 * base * haight.

Area of the parallelograms = height * base.

Area of rectangle= width * length

Area of trapezoid = 1/2 * (a + b) * height where a and b are the opposite parallel sides

The perimeters = sum of the sides of the polygons.

Are the graphs of 6 <br>y = -2x + 4 and y = 6x - 4 parallel perpendicular or neither
timurjin [86]
1st slope is -1/3. 2nd slope is 6

slope is same in parallel lines so not parallel

slopes are negative reciprocals in perpendicular lines so they aren't perpendicular

they are called oblique
