$slope= m = 1$ $"slope= m"=1"$
$y-intercept = b = 1$ $"y-intercept"="b"="1"$
$x-intercept = - 1$ $"x-intercept"=-1"$

Explanation:

$y = x - 3 + 4$ $y=x-3+4$

Simplify.

$y = x + 1$ $y=x+1$

This equation is in slope-intercept form, $y = m x + b$ $y=mx+b$ , where $m$ $m$ is the slope $+ 1$ $+1$ , and $b$ $b$ is the y-intercept $+ 1$ $+1$ . The y-intercept is the value of $y$ $y$ when $x = 0$ $x=0$ .

The point is $(0, 1)$ $(0,1)$ .

The x-intercept is the value of $x$ $x$ when $y = 0$ $y=0$ . Substitute $0$ $0$ for $y$ $y$ and solve for $x$ $x$ .

$0 = x + 1$ $0=x+1$

$- 1 = x$ $-1=x$

Switch sides.

$x = - 1$ $x=-1$ is the x-intercept.

The point is $(- 1, 0)$ $(-1,0)$

Plot the points for the x-intercept and the y-intercept and draw a straight line through the points.
