Sue and Kathy were doing their algebra homework. They were asked to write the equation of the line that passes through the points (-3,4) and (6,1). Sue wrote y - 4 = -1/3(x + 3) and Kathy wrote y = -1/3x + 3. Justify why both students are correct.

• Both equations represent the same line in different forms.

• Sue's equation is in point-slope form while Kathy's is incorrect.

• Kathy's equation is in slope-intercept form while Sue's is incorrect.

• Both equations represent different lines that happen to pass through the given points.

How many of the equations listed below represent the line passing through the points (2, 3) and (4, -7)?

5x+y=13

y+7=-5(x-4)

y=-5x+13

y+7=5(x-4)

If the number of adult tickets sold is represented by a and student tickets sold by s, which expression represents the amount of money collected at the door from the ticket sales?

• 4.50a

• 4.50(a + s)

• (3.00a)(1.50s)

• 3.00a + 1.50s
