See a solution process below:

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

First Point: For $x = 0$ $x = 0$

$y = (3 \times 0) - 1.5$ $y = (3 xx 0) - 1.5$

$y = 0 - 1.5$ $y = 0 - 1.5$

$y = - 1.5$ $y = -1.5$ or $(0, - 1.5)$ $(0, -1.5)$

Second Point: For $x = 1$ $x = 1$

$y = (3 \times 1) - 1.5$ $y = (3 xx 1) - 1.5$

$y = 3 - 1.5$ $y = 3 - 1.5$

$y = 1.5$ $y = 1.5$ or $(1, 1.5)$ $(1, 1.5)$

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

graph{(x^2+(y+1.5)^2-0.025)((x-1)^2+(y-1.5)^2-0.025)=0 [-10, 10, -5, 5]}

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

graph{(y-3x+1.5)(x^2+(y+1.5)^2-0.025)((x-1)^2+(y-1.5)^2-0.025)=0 [-10, 10, -5, 5]}

How do you graph the equation y=3x-1.5y=3x−1.5y=3x-1.5?
