Question

What are theline x - 2y = 4?O (4,0)O (-2,0)O (0,-2)O (0,4)coordinates of the x-intercept of the

Answer 1

Given the following equation of a line:

`x-2y=4`

We will find the x-intercept of the line

The x-intercept is the value of x which makes y = 0

So, we will substitute y = 0 and solve the equation for x

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

So, the x-intercept = (4, 0)

So, the answer will be (4, 0)

Answer 2

(4,0)

Explanation:

The x intercept is the point where y = 0

So we can find the x intercept by plugging in y = 0 and then solving for x

x - 2y = 4

==> plug in y = 0

x - 2(0) = 4

==> multiply 2 and 0

x = 4

The x intercept is at (4,0)

Common misconception:

Remember coordinates are written as (x,y)

The value of x at the x intercept is 4 and the value of y would be 0

So the x intercept is at (4,0) and not (0,4)
