Find the slope and y-intercept of the line with the given equation. 1. y=-25
2. y=-5/3x+7
3. 9x+3y=-81

1. The slope is 0 and the y intercept is 25

2. The slope is 5/3 and the y intercept is 7

3. The slope is -3 and the y intercept is -27

Step-by-step explanation:

1. If you graph y=25 it is a horizontal line going intersecting with the graph at 25. It doesn't change in steepness so the slop is non existent.

2. In a y=mx+b equation, the m represents the slope so whatever number takes the place of m is the slope. In this case that was 5/3. The b in the equation represents the y intercept which in this case was 7.

3. If you graph the equation it intersects the graph at -27. And from one point to another you go down 3 and over 1 meaning the slope is -3.
