Question

Draw the graph as follows?

`y=2x-1`

Answer 1

Refer to the explanation.

Explanation:

Graph:

`y=2x-1`

Determine two points on the line (The shortest distance between two points is a straight line.). I prefer to determine the x- and y-intercepts.

X-intercept: value of `x` when `y=0`

`0=2x-1`

Add `1` to both sides.

`1=2x`

Divide both sides by `2`.

`1/2=x`

x-intercept: `(1/2,0)`

Y-intercept: value of `y` when `x=0`

`y=2(0)-1`

`y=-1`

y-intercept: `(0,-1)`

Plot the two points and draw a straight line through them.
