3x - 2y = 0 and x^2 + y^2 = 4 the first equation is a line and the second is a circle.
2y = 3x solve for y in both equations
y = 3/2x to graph this start at (0,0) goover 3 and up 2 that will give you the line.
x^2 +y^2 = 4 is a circle
y^2 = 4-x^2
y = square root (4-x^2) and y = -square root (4-x^2) create a chart and plug in points between -4 and 4 to graph it good luck!
