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

Nov 20, 2017

See a solution process below:

#### Explanation:

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

First Point: For $x = 0$

$y = \left(3 \times 0\right) - 1.5$

$y = 0 - 1.5$

$y = - 1.5$ or $\left(0 , - 1.5\right)$

Second Point: For $x = 1$

$y = \left(3 \times 1\right) - 1.5$

$y = 3 - 1.5$

$y = 1.5$ or $\left(1 , 1.5\right)$

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]}
