The tables of ordered pairs represent some points on the graphs of lines h and g.

Write a system of equations in slope-intercept form to represent line h and line g.

• y = 2.5x + 1.45

  y = -5x - 6

• y = 1.45x + 2.5

  y = -5x - 6

• y = 2.5x + 1.45

  y = -0.25x - 1.25

• y = 1.45x + 2.5

  y = -0.25x - 1.25
