Exam 8: Graphs, Functions, and Systems of Equations and Inequalities

Graph the following line. -Through $( 4 , - 1 ) , \mathrm { m } = - \frac { 3 } { 4 }$

Find the y- and x-intercepts for the equation. Then graph the equation. - $6 x - 18 y = 0$

Find the slope-intercept form of the equation for the line shown. -

$\text { Locate the point on the rectangular coordinate system. }$ -(4, -5)

Complete the ordered pairs. Then graph the equation. - $2 x - y = 2$ $(0,),(, 0),(2,)$

Find the slope of the line through the points. -(1, 4)and (3, 4)

Determine the quadrants in which the given point (x,y)may lie. -xy > 0

Use the distance formula to find the distance between the pair of points. - $( - 2 , - 1 )$ and $( 2,1 )$

Graph the circle. - $x^{2}+(y-1)^{2}=9$

Graph the following line. - $\mathrm{m}=0 ; \text { through }(5,2)$

Graph the circle. - $( x - 3 ) ^ { 2 } + ( y - 1 ) ^ { 2 } = 4$

Solve the problem. -The enrollment at State University for 2002 was 12 thousand students. The projected enrollment for 2008 is 28 thousand students. Use the midpoint formula to estimate the enrollment for 2005.

Use this graph to answer the question. -What month in 2009 had the highest sales?

Find the center and radius of the circle. - $x ^ { 2 } + y ^ { 2 } + 18 x + 2 y = - 46$

Find the midpoint of the line segment joining the two points. - $( 4 , - 4 )$ and $( - 2,8 )$

Find the center and radius of the circle. - $x ^ { 2 } + y ^ { 2 } = 9$

Decide whether the pair of lines is parallel, perpendicular, or neither. -The line through (-1, -3)and (2, -2)and the line through (-5, 20)and (-2, -6)

Choose one of the four lines graphed which most closely resembles the graph of the given equation. - $y = - 3 x - 6$

Find the average rate of change. Use appropriate units.

Decide whether the statement is true or false. -If a point lies on the y-axis, its x-coordinate is zero.
