See a solution process below:

Explanation:

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

First Point:

For x = 0

y = (3/4 * 0) - 5

y =0 - 5

y = -5 or (0, -5)

Second Point:

For x = 4

y = (3/4 * 4) - 5

y =3 - 5

y = -2 or (4, -2)

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

graph{(x^2+(y+5)^2-0.075)((x-4)^2+(y+2)^2-0.075)=0 [-15, 15, -7.5, 7.5]}

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

graph{(y-3/4x+5)(x^2+(y+5)^2-0.075)((x-4)^2+(y+2)^2-0.075)=0 [-15, 15, -7.5, 7.5]}
