Question

If a line has a slope of 3 and contains the point (-1,4), what is its equation inpoint-slope form?A. y+ 1 = 3(x-4)B. y-1 = 3(x-4)C. y-4 = 3(x+1)O D. Y-4 = 3(x-1)SHIRMAT

Answer 1

Use the point slope equation to solve the problem.

`y-y1=m(x-x1)`

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

Replace for the given values:

`\begin{gathered} y-4=3(x-(-1)) \\ y-4=3(x+1) \end{gathered}`

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