Question

What is the point - slope form of an equation for the line that has the indicated slope and contains the given point?

slope = 1.3;(-6.1, 5.3)

A) y - 5.3 = 1.3 (x - 6.1)

B) y + 5.3 = 1.3 (x - 6.1)

C) y - 1.3 = 5.3 (x + 6.1)

D) y - 5.3 = 1.3 (x + 6.1)

Answer 1

D

Explanation:

y - 5.3 = 1.3 (x + 6.1)

Answer 2

D

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 = 1.3 and (a, b) = (- 6.1, 5.3), hence

y - 5.3 = 1.3(x + 6.1) ← in point-slope form
