If a line has a slope of 3 and contains the point 14 what is its equation inpointslope formA y 1 3x4B y1 3x4C y4 3x1O D Y4 3x1SHIRMAT class=

Respuesta :

Use the point slope equation to solve the problem.

[tex]y-y1=m(x-x1)[/tex]

Where m is the slope and x1 and y1 are the coordinates of the given point.

Replace for the given values:

[tex]\begin{gathered} y-4=3(x-(-1)) \\ y-4=3(x+1) \end{gathered}[/tex]

Which means the right answer is C. y-4=3(x+1).
