Answer:

y = - 50x + 500

or

50x + y = 500

Explanation:

Line is passing through the points (2, 400) & (4, 300)

Slope of the line = (400 - 300)/(2 - 4) = 100/(-2) = - 50

Equation of line in point slope form is given as:

y - 300 = - 50(x - 4)

y - 300 = - 50x + 200

y = - 50x + 200 + 300

y = - 50x + 500

50x + y = 500
