Question

Write the equation of the line that passes through (1, 3) and has a slope of 2 in point-slope form.
y – 1 = 2(x – 3)
y – 3 = 2(x – 1)
x – 1 = 2(y – 3)
x – 3 = 2(y – 1)

Answer 1

just plug in the points and the slope which is m into the point slope formula

\[m(x-x_{0}) = y-y_{0}\]

Answer 2

Thanks:)

Answer 3

What does this equation become after you've substituted 2 for m?
After you've substituted the coordinates (1,3)?
