Question

How do you graph the equation `y=2x-1`?

Answer 1

See a solution process below:

Explanation:

First, solve the equation for two points:

For `x = 0`: `y = 2(0) - 1 = 0 - 1 = -1` giving: `(0, -1)`

For `x = 5`: `y = 2(5) - 1 = 10 - 1 = 9` giving: `(5, 9)`

Plot these two points, then draw a straight line through the points:

graph{(y - 2x + 1)((x)^2+(y+1)^2-0.25)((x-5)^2+(y-9)^2-0.25)=0 [-30, 30, -15, 15]}
