Question

A line has a y-intercept and a slope of 0. What is the line’s equation?

x + y = - 1

y = x - 1

x = -1

y = -1

Answer 1

The answer is y= -1

When the slope is 0, we refer to the line as a constant function. In slope intercept form, the line is equal to y = mx + b



"m" is the slope, and "b" is the y-intercept.



Let's replace those in the function.



y = 0*x - 1



0 multiplied by anything is 0



y = 0 - 1

y = -1
