Answer:
47.88
Explanation:
To find your y-intercept, set the x value to zero.
When x is zero, you are crossing the y-axis, so that is where the line is intercepting y.
When you set x to equal 0, you get
y = 0.577(0) + 47.88
Anything times zero is zero, so you are left with
y = 0+47.88
y = 47.88
I am not sure how the information given in the first part is relevant as they already give you an equation in the form y = mx+b, b is the y-int.
