Question

how to graph y=x-5 thanks

Answer 1

what's the variable

Answer 2

whats the variable?

Answer 3

We'll have to recall some knowledge from analytic geometry.
We know that it's a line, since it's a first degree equation, and we know that the line equation in point-slope formula has this form:
\[y=mx+b\]
where m, is the slope and b the OY intersection.
We know that OY intersection implies that x=0 and the slope is just the invlination the line has respectively to the x or y coordinates.
so we are asked to graph:
\[y=x-5\]
theres no number on the coeficient of x, meaning that there's a "1".
So we have a slope of 1, and a y itersection of -5.
in order to find the OX intersection, we just make y=0:
\[0=x-5\]
\[x=5\]
So when x takes the value of 5, we see that it cuts the OX coordiantes.
so the graph would look like this:
