drag the red and blue dots along the x - axis and y - axis to graph 4x + 2y = 20.

Explanation:

Step1: Find x - intercept

Set (y = 0) in (4x+2y = 20). Then (4x=20), so (x = 5).

Step2: Find y - intercept

Set (x = 0) in (4x+2y = 20). Then (2y=20), so (y = 10). The red dot should be at ((5,0)) on the x - axis and the blue dot should be at ((0,10)) on the y - axis.

Answer:

Red dot at ((5,0)), blue dot at ((0,10))
