Question

Given the point (1, 3) and the slope -2, write the equation for the line in point-slope form

Answer 1

y - 3 = - 2(x - 1)

Explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 2 and (a, b) = (1, 3) , thus

y - 3 = - 2(x - 1) ← in point- slope form
