Answer:
y = - 50x + 500
or
50x + y = 500
Step-by-step 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
