line with equation y=ax+b,ab is not equal to 0,x-intercept is twice the y

Question

options are the slope of the line (2)1/2

Answer 1

y-intercept = (0, b)

x-intercept = (2b, 0)

 

m = (y₁ - y₂) / ( x₁ - x₂)

m = (b - 0) / (0 - 2b)

m = b / -2b

m = 1 / -2

m = -1/2

 

The slope of the line is -1/2
