Question

How do you graph the function `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]}
