- The line y=4x+5 has a slope of 4 and intersects the y-axis at 5.

- The line y=-1x+0 can be written as y=-x, has a slope of -1 and a y-intercept of 0.

- The line y=0x+3 can be written as y=3, has a slope of 0 and a y-intercept of 3.

- The line y=0x+0 can be written as y=0, and is a horizontal line with y-intercept 0.

- The linear relation y=mx+b represents a set of ordered pairs (x,y) passing through the point (0,b).

The b is called the line's y-intercept and the m is called the line's slope =(rise/run) = rate of change.
