See a solution process below:

First, solve for two points which solve the equation and plot these points:

First Point: For #x = 0#

#y = (-2 * 0) + 3#

#y = 0 + 3#

#y = 3# or #(0, 3)#

First Point: For #x = 2#

#y = (-2 * 2) + 3#

#y = -4 + 3#

#y = -1# or #(2, -1)#

We can next plot the two points on the coordinate plane:

graph{(x^2+(y-3)^2-0.035)((x-2)^2+(y+1)^2-0.035)=0 [-10, 10, -5, 5]}

Now, we can draw a straight line through the two points to graph the line:

graph{(y + 2x - 3)(x^2+(y-3)^2-0.035)((x-2)^2+(y+1)^2-0.035)=0 [-10, 10, -5, 5]}
