See the solution process below:

Divide each side of the equation by $3.5$ $color(red)(3.5)$ to isolate the $x$ $x$ term:

$\frac{3.5 x}{3.5} = \frac{10.5}{3.5}$ $(3.5x)/color(red)(3.5) = 10.5/color(red)(3.5)$

$(color(red)(cancel(color(black)(3.5)))x)/cancel(color(red)(3.5)) = 3$

$x = 3$

By definition this is a vertical line where $x$ has a value of $3$ for every value of $y$ including when $y = 0$ . Therefore:

The x-intercept is $3$ or $(3, 0)$

Because this is a vertical line at $x = 3$ there is no y-intercept.
