Question

How do you graph `y=3.5x`?

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 = 3.5 * 0`

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

Second Point:

For `y = 2`

`y = 3.5 * 2`

`y = 7` or `(2, 7)`

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

graph{(x^2+y^2-0.075)((x-2)^2+(y-7)^2-0.075)=0 [-20, 20, -10, 10]}

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

graph{(y-3.5x)(x^2+y^2-0.075)((x-2)^2+(y-7)^2-0.075)=0 [-20, 20, -10, 10]}
