Answer:

  • $1325

Explanation:

Translate the given into two pairs of coordinates:

  • (800, 975) and (1100, 1125)

Work out the equation of the line passing through both of the points.

Find the slope:

  • m = (1125 - 975) / (1100 - 800) = 0.5

Find the y-intercept:

  • 975 = 0.5*800 + b
  • 975 = 400 + b
  • b = 975 - 400
  • b = 575

The line is:

  • y = 0.5x + 575

Find the value of y when x = 1500:

  • y = 0.5*1500 + 575 = 1325
