Answer:
y = -x + 3
Explanation:
If you are asking for the equation of the function in slope-intercept form, this should be your answer.
The slope-intercept for in its general equation is:
y = mx + b
In this equation, "m" is the slope and "b" is the y-intercept.
Since you were given the value of these variables, you can plug them in to get your final equation.
slope = m = -1
y-intercept = b = 3
y = mx + b
y = -1x + 3
y = -x + 3
