What is the y-intercept of the equation:  y = 2x - 3

Find the value of y when x = 2

Slope is another word for:

• Initial Value

• Rate of Change

• Change in Y's

• Y-intercept

• slope: 1/6   y-intercept:  4 

• slope: 1/5   y-intercept:  5 

• slope: 5/1   y-intercept:  5 

• slope: 1   y-intercept:  5
