The line through (8,-3) with slope 8

  8x -y = 67

Step-by-step explanation:

When given a point and slope, it is useful to start with the point-slope form of the equation of a line:

  y -k = m(x -h) . . . . . for a line with slope m through point (h, k)

Filling in your numbers, this is ...

  y +3 = 8(x -8)

  8x -64 -y -3 = 0 . . . . . . subtract (y+3)

  8x -y = 67 . . . . . . . . . . . add 67 to get standard form

answer: 2530
