Answer:

  y = 5x -2

Step-by-step explanation:

The slope is given by the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (8 -3)/(2 -1) = 5

The y-intercept is given by the formula:

  b = y -mx

  b = 3 -5(1) = -2

Then the slope-intercept form equation is ...

  y = mx +b

  y = 5x -2 . . . . . . . . using the m and b we found above
