Write the equation for a line that is perpendicular to the line y = −1 and passing
1 answer:
Answer:
x= 12
Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the gradient and c is the y-intercept.
y= -1
y= 0x -1
The given line, y= -1, is a horizontal line as it has a gradient of zero.
A line perpendicular to a horizontal line is a vertical line, and its equation is written as x= ___.
Since the vertical line passes through the point (12, -39), its equation is x= 12.

A rational number is a number which can be expressed as a fraction whose numerator and denominator are both integers and whose denominator is not equal to zero. Rational numbers include all integers, fractions, mixed numbers, and some decimal numbers.
Note : All terminating and repeating decimal numbers are rational numbers because those numbers can be expressed as a fraction. On the other hand, a non repeating number and non terminating decimal, like square root of 2, is an irrational number.
