Answer:
slope: 4
y intercept: -4
Explanation:
the equation you're given is in y = mx + b format
the "b" in the equation is the y intercept
the x and y are the variables
and the "m" is the slope
so in this case, the "m" would be 4 because it is the number right next to x
the -4 would be the "b" in this because it is after the "y=" and does not have a variable
