Given M=126.67 and (0.426, 0.406) what is the y intercept from the slope equation y = 0.577x + 47.88

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.
