Question

graph this function:
( y = x + 80 )
click to select points on the graph.

Explanation:

Step1: Find y-intercept (x=0)

Substitute $x=0$ into $y=x+80$:
$y=0+80=80$
Point: $(0, 80)$

Step2: Find x-intercept (y=0)

Substitute $y=0$ into $y=x+80$:
$0=x+80 \implies x=-80$
Point: $(-80, 0)$

Step3: Find a third test point

Substitute $x=20$ into $y=x+80$:
$y=20+80=100$
Point: $(20, 100)$

Answer:

Plot the points $(0, 80)$, $(-80, 0)$, and $(20, 100)$, then draw a straight line through them to graph $y=x+80$.
