What is the equation in point slope form of the line that passes through the point (−1, −3) and has a slope of 4?



y+3=4(x+1)

y+1=4(x+3)

y−3=4(x−1)

y−1=4(x−3)

Answer 1

Answer: y+3 = 4( x + 1)

Explanation:

The equation in point slope form is given as :

y -
`y_(1)` = m ( x -
`x_(1)` ) , where m is the slope

slope = 4

point given : (-1,-3)

Using the formula :

y -
`y_(1)` = m ( x -
`x_(1)` )

and substituting the value , we have

y - (-3) = 4 (x -{-1} )

y+3 = 4( x + 1)
