(see below for an alternative to using the slope)

Explanation:

Given $y = 5 x - 5$

Select a few (arbitrary) values for $x$, say $x \in \left\{0 , 1 , 2\right\}$

Evaluate corresponding values for $y$ using the given equation:

{:(color(black)x,color(white)("XX"),color(black)y), (0,,-5),(1,,0),(2,,5) :}

Plot each pair on the Cartesian plane
and draw a line through the resulting points:
