Row 1, Col 1 Determine the domain and range of the given relation. {(5,25),(6,36), (7,49), (8,64)} D: { 5,6,7,8} R: { 25,36,49,64}

1,2 Write an equation in slope intercept form that contains (-8,1) and (-4, 6) y= (5/4)x + 11

1,3 Find the slope for the given rise and run. rise: 6 and run: -6 m = -1

1,4 What are the two different ways you can calculate slope? m = rise/run and m = (y 2 –y 1 )/(x 2 -x 1 )

2,1 Determine whether the relation is function. Explain. {(7,8),(1,3), (9,2), (2,8)} Yes, because the domain doesn’t repeat.

2,2 Write the equation in standard form: 3y = -4x x + 3y = 27

2,3 Find the slope of the line that contains the given pair of points. (1,-4) and (-7,-4) m = 0

2,4 What are the three different forms of equations we have learned in this unit? Slope-intercept, Standard, Point-slope

3,1 Club X charges an initial fee of $50 for use of the club with an additional cost of $34 per month. Make a table for 1-4 months, write an equation, and find the domain and range. y = 34x + 50, D:{1, 2, 3, 4} R:{84, 118, 152, 186}

3,2 Write an equation in point-slope form for the line that contains the given points: (1,-5) and (6,3). Use (1,-5) as your point of choice. y + 5 = 8/5(x-1)
