What is the equation of a line, in point-slope form, that passes through (−2, −6) (−2, −6) and has a slope of  1/3?

Verified Answer :

miriyu

point-slope form is y - y1 = m(x - x1)

plug in the given slope and the given point

y - (-6) = (1/3)(x - (-2))

then simplify

y + 6 = (1/3)(x + 2)

Answer:

\(y+6=\frac{1}{3}(x+2)\)

Step-by-step explanation:

General equation of point slope form : \(y-y_1=m(x-x_1)\)

where m is the slope

Point = \((x_1,y_1)=(-2,-6)\)

Slope = \(m = \frac{1}{3}\)

Substitute the values in general form of point slope form .

\(y-y_1=m(x-x_1)\)

\(y-(-6)=\frac{1}{3}(x-(-2))\)

\(y+6=\frac{1}{3}(x+2)\)

This can be simplified further

\(y+6=\frac{1}{3}x+\frac{2}{3}\)

\(y=\frac{1}{3}x+\frac{2}{3}-6\)

\(y=\frac{1}{3}x-\frac{16}{3}\)

Hence the equation of a line, in point-slope form, that passes through (−2, −6) and has a slope of  1/3 is \(y+6=\frac{1}{3}(x+2)\)
