Question

How do you graph `f(x)=1/2x+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`

`f(0) = (1/2 * 0) + 1`

`f(0) = 0 + 1`

`f(0) = 1` or `(0, 1)`

Second Point: For `x = 2`

`f(2) = (1/2 * 2) + 1`

`f(2) = 1 + 1`

`f(2) = 2` or `(2, 2)`

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

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