Identify an equation in point-slope form for the line perpendicular to y=-1/3x-6 that passes through (–1, 5).

1 answer:

4 0

y=-1/3x-6 slope = -1/3
perpendicular lines, slope is opposite and reciprocal

so slope = 3
passes through (–1, 5).

Point-slope is point-slope form y-y₁=m(x-x₁)
so equation
y - 5 = 3(x + 1)

hope it helps

Oduvanchick [21]

$\huge \mathtt \blue{answer}$

Here, “p” is a numerator and “q” is a denominator. The examples of rational numbers are 6/5, 10/7, and so on. The rational number is represented using the letter “Q”. Like real numbers, the arithmetic operations, such as addition, subtraction, multiplication, and division are applicable to the rational numbers.
