Q1:  Graph the equation y = 2x + 6 by finding the x- and y-intercepts and a check point.

Show your calculation of the x- and y-intercepts, and check point. In your graph, label the intercepts.

 

Q2: Property taxes have continued to increase year after year. Note that in 1990, a home's taxes were $1200, and that same home's taxes were $2600 in 2010. If x represents they year and y the real estate tax:

A. Calculate the slope. (3 points)

B. Explain, the concept of slope

 

Q3: 

For each of the equations below: (a) rewrite each in slope-intercept form by solving for y; (b) identify the slope; and (c) identify the y-intercept.

1. 5y = 10x + 4   

2. 3x - 4y = 7

 

Show all work.
