Answer:
- y = 3x + 4
- y =
x - 1
- y = 4
- undefined
Step-by-step explanation:
Slope-intercept form is written in the form: <em>y </em>=<em> mx </em>+<em> b</em>. Leave the y and x as they are. The m is the slope of the graph. The b is the y-intercept of the graph. For number three, the slope of a horizontal line is 0. For number four, the slope of a vertical line is undefined.
