Question

Explain CIRCLE COMMAND in QBASIC graphics.​

Answer 1

Explanation:

Solve equation [1] for the variable y

[1] y = -x + 7

// Plug this in for variable y in equation [2]

[2] 3x - (-x +7) = 1

[2] 4x = 8

// Solve equation [2] for the variable x

[2] 4x = 8

[2] x = 2

// By now we know this much :

x = 2

y = -x+7

// Use the x value to solve for y

y = -(2)+7 = 5

Solution :

{x,y} = {2,5}
