Question

How do you find the slope & y-intercept of the equation `y=-7`?

Answer 1

slope = 0 , y-intercept = - 7

Explanation:

y = - 7 is a special form of the equation of a line in that it is parallel
to the x-axis and therefore has a slope of zero. This line is special in
that it passes through all the points in the plane whose y-
coordinates are - 7. It therefore has a y-intercept of - 7 .

Here is it's graph:
