What is the x-intercept of y=-4x+4?

The linear equation form is $y = m x + c$ :)

Explanation:

Where:
$m$ is the gradient of the equation and $c$ is the $y$-intercept.
To find the intercepts, substitute 0 into either of the $x$ or $y$ values.

Therefore, to find the $x$-intercept, sub 0 into the $y$ value.
In equation form, that is:
$y = m x + c$
$0 = - 4 x + 4$
$4 x = 4$
$x = 1$

Therefore, the coordinates of the $x$-intercept are $\left(1 , 0\right)$. Hope this helps!
