Question

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

Answer 1

y=2x+1

Explanation:

Well if the slope is the gradient you have the formula

y−y1=m(x−x1)

so the equation of the line becomes:

y−3=2(x−1)

⇒y−3=2x−2

y=2x+1

(in form)

y=mx+b

or

2x−y+1=0(ax+by+c)

(form)
