Question

How do you graph `y=5x-1`?

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 = (5 * 0) - 1`

`y = 0 - 1`

`y = -1` or `(0, -1)`

Second Point: For `x = 1`

`y = (5 * 1) - 1`

`y = 5 - 1`

`y = 4` or `(1, 4)`

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

graph{(x^2+(y+1)^2-0.035)((x-1)^2+(y-4)^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 - 5x + 1)(x^2+(y+1)^2-0.035)((x-1)^2+(y-4)^2-0.035)=0 [-10, 10, -5, 5]}
