Answer:

  • y = 0.8x
  • y = 0.8x -3.2

Step-by-step explanation:

Each line has a rise of 4 units for each run of 5 units to the right. That makes the slope be ...

  m = rise/run = 4/5 = 0.8

The top line shows a simple proportional relationship, so its equation is ...

  y = 0.8x . . . . . top line

The bottom line has the same slope and a y-intercept of -3.2. Its slope-intercept form equation is ...

  y = mx +b . . . . . line with slope m and y-intercept b

  y = 0.8x -3.2 . . . . bottom line
