Question

How do you graph `y=25x+150`?

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 = (25 * 0) + 150`

`y = 0 + 150`

`y = 150` or `(0, 150)`

Second Point: For `x = 10`

`y = (25 * 10) + 150`

`y = 250 + 150`

`y = 400` or `(10, 400)`

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

graph{(x^2+(y-150)^2-100)((x-10)^2+(y-400)^2-100)=0 [-500, 500, -100, 500]}

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

graph{(y-25x-150)(x^2+(y-150)^2-100)((x-10)^2+(y-400)^2-100)=0 [-500, 500, -100, 500]}
