Answer:
y = -x + 9
Step-by-step explanation:
the equation of a line is given by y = mx + b where m Is the slope and b is the y intercept.
as shown in the graph, the y intercept is 9.
how to find the slope:
the slope is rise over run and as we can see that the points move down once and to the right once at every exact point. hence, the slope is -1.
the equation: y = -x +9
