Two perpendicular lines intersect at the origin if the slope of the first line is 3,what is the equation of the second line

Mathematics

· Perpendicular lines have slopes that are opposite reciprocals of each other

· Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept


If the slope of the first line is 3, the slope of the second line is -1/3. Since the lines intersect at the origin, neither of them have a y-intercept.


Answer:

C) y = -1/3x

I just want to make sure or is it b?

I believe the answer should actually be

C.) It is a one to one function

A one to one function is a function in which the x and y values never repeat. Each value of x is different every time, and they never have the same values of y.

Which of the lines graphed has a slope of -1/2 and a y-intercept of 3
MAXImum [283]

Answer:

The correct option is C).

Figure show the line with slope of -1/2 and a y-intercept of 3

Step-by-step explanation:

The equation of line is given by y=mx+c.

Where m is slope and c is y-intercept.

Given that line has slope

m=\frac{-1}{2} and c=3

Thus equation of line will be

y=mx+c.

y=\frac{-1}{2}x+3

To plot the line we need at least two points

Take x=0

y=\frac{-1}{2}x+3

y=\frac{-1}{2}0+3

y=3

The required point is A(0,4)

Take x=2

y=\frac{-1}{2}2+3

y=2

The required point is B(2,2)

Using this points to graph the given equation of line

Figure show the line with a slope of -1/2 and a y-intercept of 3

The correct option is C).

Answer:

1, 2, 3, 4

Step-by-step explanation:

  1. 4 1/3·1 = 4 1/3 Good
  2. 7 1/3·2 2/5 = 22/3·12/5 = 110/15·36/15= 3960/225 = 17 3/5 Good
  3. 6 2/3·1/2 = (6 2/3)/2 = 3 1/3 Good
  4. 4 1/2·2 1/6 = 9/2·13/6 = 27/6·13/6 = 9 3/4 Good
  5. 5·3 1/4 = 20/4·13/4 = 16 1/4 Doesn't Work
