Question

Can you graph y=2x-4

Answer 1

Here, we want to graph the given linear equation

To do this, we need the x and the y intercepts

The general linear equation form is;

`y\text{ = mx + b}`

where b here is -4

The point is thus (0,-4)

To get the x-intercept, we set y to 0

We have this as;

`\begin{gathered} 0\text{ = 2x-4} \\ 2x\text{ = 4} \\ x\text{ = }(4)/(2) \\ \text{x = 2} \end{gathered}`

The x-intercept is thus (2,0)

So by joining the points (2,0) and (0,-4) with a straight line and extending it, we have successfully graphed it
