Question

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

Answer 1

y − 3 = 2(x − 1)

Explanation:

The point-slope form of the equation of a line with slope m through point (h, k) is ...

y -k = m(x -h)

You have m=2, h=1, k=3, so the equation is ...

y -3 = 2(x -1)
