Graphing Slope Intercept

Graphing Slope Intercept

Coordinate Plane

Graphing a Point

Always written in the form (x,y)

​

The x-value tells us to move left or right

​

The y-value tells us to move up or down

​When finding the equation of a graph, you need to find both the slope and y-intercept.

​

• Slope : ​rise/run

  ​

• y-intercept: Find where it crosses the y-axis.​

Identifying Basic Slopes

Slope: the 'steepness' of a line.

​

There are FOUR basic categories for SLOPES

POSITIVE SLOPE

NEGATIVE SLOPE

SLOPE OF ZERO

UNDEFINED SLOPE
