Question

Complete the equation of the line through (3, -1) and (4, 7)​

Answer 1

Answer:

  y = 8x -25

Step-by-step explanation:

The two-point form of the equation of a line can be used.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (7-(-1))/(4-3)(x -3) +(-1)

  y = 8(x -3) -1

  y = 8x -25 . . . . slope-intercept form of the equation

We don't know what you're starting with, so we don't know how to "complete the equation." Perhaps the above equation is sufficient for the task.
