Question 62215
y=mx+b [slope-intercept form of a line]
y=any y value of the line
m=the slope of the line
x=any corresponding x value of the line
b=the y-intercept (the point where the line crosses the y-axis at point (0,b)]
.
y = 2x - 3
Identify the y-intercept.  
Use the y-intercept as a starting point and use the slope to find other points.
m=2
y-intercept = (0, -3)
