Slope = $-5/22$

$y$ -intercept is $-9$ and the point is $(0,-9)$

$x$ -intercept is $-3.6$ and the point is $(-3.6,0)$

First, we find the slope and $y$ -intercept

Now, the equation of a line is of the form $color(red)(y=mx+c)$

Where, $m$ is the slope of the line and $c$ is the $y$ -intercept.

Let us write the given line in the standard form:

$y=-(5x)/2-18/2$

$=>y=-(5x)/2-9$

Comparing $y=mx+c$ to the given equation, $y=-(5x)/2-9$

$m=-5/2$ and $c=-9$

$=>$ Slope $= -5/2$ and $y$ -intercept $= -9$

Next, we work out the $x$ -intercept.

The $x$ -intercept is the point where the line cuts the $x$ -axis. i.e. to find the point when $y=0$ .

Pretty simple.

Here is a step-by-step calculate the $x$ -intercept .

$x$ -intercept is $-3.6$ .
