Answer:
y = -5/4x +11/4
Explanation:
We can use the slope intercept form of the equation
y = mx+b where m is the slope and b is the y intercept
y = -5/4x +b
Substitute the point into the equation
-1 = -5/4(3) +b
-1 = -15/4 +b
Add 15/4 to each side
-4/4+15/4 = -15/4+15/4 +b
11/4 =b
The equation is
y = -5/4x +11/4
