Question

How do you graph the line `Y=3x-4`?

Answer 1

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 * 0) - 4`

`y = 0 - 4`

`y = -4` or `(0, -4)`

Second Point: For `y = 2`

`y = (3 * 2) - 4`

`y = 6 - 4`

`y = 2` or `(2, 2)`

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

graph{(x^2+(y+4)^2-0.04)((x-2)^2+(y-2)^2-0.04)=0 [-10, 10, -5, 5]}

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

graph{(y-3x+4)(x^2+(y+4)^2-0.04)((x-2)^2+(y-2)^2-0.04)=0 [-10, 10, -5, 5]}
