The slope is $- 1.25$ $-1.25$ and the $y$ $y$ - intercept is $3$ $3$ .

Explanation:

The equation of a line in slope-intercept form is

$y = m x + b .$ $y=mx+b.$

$m$ $m$ is the slope

$b$ $b$ is the $y$ $y$ -intercept.

Put

$y = 3 - 1.25 x$ $y=3-1.25x$

into that form and you get....

$y = - 1.25 x + 3$ $y= -1.25x + 3$

So

$m$ $m$ is $- 1.25$ $-1.25$

$b$ $b$ is $3$ $3$

Have a great day!

Slope $= (- 1.25)$ $= (-1.25)$
y intercept $= 3$ $=3$

Explanation:

One of the common ways of expressing a linear equation is in slope-intercept form.

In general the slope-intercept form looks like:
$XXX y = m x + b$ $color(white)("XXX")y=color(green)mx+color(red)b$
where $m$ $color(green)m$ is the slope and $b$ $color(red)b$ is the $y$ $y$ -intercept.

The given equation $y = 3 - 1.25 x$ $y=3-1.25x$ can be rearranged into slope-intercept form as:
$XXX y = - 1.25 x + 3$ $color(white)("XXX")y=color(green)(-1.25)x+color(red)3$
with a slope of $- 1.25$ $color(green)(-1.25)$ and a $y$ $y$ -intercept of $3$ $color(red)3$
