Slope = $- \frac{5}{22}$ $-5/22$

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

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

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

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

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

Let us write the given line in the standard form:

$y = - \frac{5 x}{2} - \frac{18}{2}$ $y=-(5x)/2-18/2$

$\Rightarrow y = - \frac{5 x}{2} - 9$ $=>y=-(5x)/2-9$

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

$m = - \frac{5}{2}$ $m=-5/2$ and $c = - 9$ $c=-9$

$\Rightarrow$ $=>$ Slope $= - \frac{5}{2}$ $= -5/2$ and $y$ $y$ -intercept $= - 9$ $= -9$

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

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

Pretty simple.

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