Question

Graph eat equation rewrite i.n slope-intercept form first if necessary.Y=2x-1

Answer 1

Given:

`y=2x-1`

Find-:

Graph of equation

Explanation-:

The equation is:

`y=2x-1`

The general form of a straight line is:

`y=mx+c`

Where,

`\begin{gathered} m\text{ = slope} \\ \\ c=\text{ y-intercept} \end{gathered}`

At x = 0 value of y is:

`\begin{gathered} y=2x-1 \\ \\ y=2(0)-1 \\ \\ y=-1 \end{gathered}`

At y = 0 value of x is:

`\begin{gathered} y=2x-1 \\ \\ 0=2x-1 \\ \\ x=(1)/(2) \end{gathered}`

So the line passes the point (0,-1) and (1/2, 0).

The graph of the line is:
