Question

The point (5, 1) lies on a line with a slope of –3. What is the equation of the line? (hint: how can you translate the point (5, 1) onto the point (0, 0)?)a.y + 1 = –3(x –5)b.y + 1 = –3(x + 5)c.y –1 = –3(x –

Answer 1

y - 1 = - 3(x - 5)

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 = - 3 and (a, b) = (5, 1), hence

y - 1 = - 3(x - 5) ← equation of line
