The x-intercept is $(-7/3,0)$ .

The y-intercept is $(0,-7)$ .

$y=3x-7$

The x-intercept is the value for $x$ when $y=0$ .

Substitute $0$ for $y$ .

$0=3x-7$

Subtract $3x$ from both sides.

$-3x=-7$

Divide both sides by $-3$ .

$x=-7/3$

The y-intercept is the value of $y$ when $x=0$ .

Substitute $0$ for $x$ .

$y=3(0)-7$

$y=-7$

The x-intercept is $(-7/3,0)$ .
The y-intercept is $(0,-7)$
