What is the significance of a slope of zero in a linear equation?
A slope of zero in a linear equation means that the line is horizontal.
How do you find the y-intercept from two points?
Find the slope, then plug one point in for x and y, the slope in for m, then solve for b in y=mx+b
How many points are on a line?
there are infinite points on a line
