Question

graph this function:
$y = x - 9$
click to select points on the graph.

Explanation:

Step1: Find y-intercept (x=0)

Substitute $x=0$ into $y=x-9$:
$y=0-9=-9$
Point: $(0, -9)$

Step2: Find x-intercept (y=0)

Substitute $y=0$ into $y=x-9$:
$0=x-9 \implies x=9$
Point: $(9, 0)$

Step3: Choose a third point

Substitute $x=5$ into $y=x-9$:
$y=5-9=-4$
Point: $(5, -4)$

Answer:

Plot the points $(0, -9)$, $(9, 0)$, and $(5, -4)$, then draw a straight line through them to graph $y=x-9$.
