Question

A line that includes the point (

-
3,1) has a slope of
-
6. What is its equation in point-slope form?

Answer 1

point slope form of equation is

y - 1 = -6 (x + 3)

Explanation:

point (-3,1)

'slope = -6

formula for point slope form of equation is

y - y1 = m (x- x1)

(x1,y1) is the point and m is the slope

Given (-3,1) is the point and slope m= -6

(-3,1) so x1=-3 and y1=1

Plug in all the values in the formula

y - y1 = m (x- x1)

y - 1 = -6 (x- (-3))

y - 1 = -6 (x + 3)
