Question

A horizontal line has an equation of the form?

Answer 1

@aum

Answer 2

is it y=mx+b

Answer 3

All points on the horizontal line have the same y-value no matter what x is.

So y = b is the equation of a horizontal line.

Answer 4

thats not one of my choices

Answer 5

Or you can say horizontal line has a slope of zero. So m = 0.

Answer 6

x = a, where a is any real number
y = a, where a is any real number

Answer 7

or y=1

Answer 8

y = constant is the equation of a horizontal line.

Answer 9

y = a

Answer 10

thanks

Answer 11

what about a vertical one

Answer 12

y = constant is the equation of a horizontal line.
whether you call the constant 'a' or 'b' or 'c' does not matter.
But in your answer choices they chose to call it 'a'. Same thing.

Answer 13

y = a, where a is any real number

y = mx + b

x = 1

x = a, where a is any real number

Answer 14

For vertical line, the equation is x = a, where a is any real number.

Answer 15

The slope of a vertical line is:

undefined

zero

1

-1

Answer 16

undefined.

Answer 17

what about horiontal

Answer 18

horizontal

Answer 19

slope of horizontal line = 0.

Answer 20

ty

Answer 21

Horizontal line makes an angle of zero with x-axis.
slope = tan(0) = 0.

Vertical line makes an angle of 90 degrees with x-axis.
slope = tan(90) is undefined.
