Slope-Intercept Form and Slope

Write an equation  
m = 5/4 through (-4, -3)

• y = 5/4x +2

• y = -5/4x + 2

• y = 2x - 5/4

• y = 3/4x + 2

What is the Slope represented in this table?

The slope is defined as ​ (a)  

The y - intercept is where the line graphed line crosses ​ (b)  

The x - intercept is where the line crosses ​ (c)  

A table provides you with independent variables that are ​ (d)  

A table provides you with dependent variable that are ​ (e)  

• rise over run

• the y-axiz

• the x-axix.

• x - coordinates

• y - coordinates
