Exam 4: Graphing Linear Equations

Solve the problem. -Over the years, State University has seen an increase in the number of students majoring in Native American Studies. The graph below shows the number of Students with this major for the past several years. Does the graph display a linear relationship?

By observing the vertical and horizontal change of the line between the two points indicated, determine the slope of the line. -

Graph by plotting points. Plot at least three points for the graph. -

Write the equation of the line, with the given properties, in slope-intercept form. -Through (-6, -6) and (-8, -5)

Graph the line with the given slope that goes through the given point. -through (2, 4) with m = 0

Graph the line with the given slope that goes through the given point. -through (-3, -4) with slope undefined

Determine which line (the first or the second) has the greater slope. -

Graph by plotting points. Plot at least three points for the graph. -

Indicate whether the distinct lines, line 1 and line 2 are parallel, perpendicular, or neither. -x + 11y = 1

Determine whether the pair of lines are parallel, perpendicular, or neither. -6x + 2y = 8 12x + 4y = 19

Graph using the x- and y-intercepts. -

Graph using the x- and y-intercepts. -

Solve the problem. -A gas station sells 4820 gallons of regular unleaded gasoline in a day when they charge $1.35 per gallon, whereas they sell 3852 gallons on a day that they charge $1.40 per gallon. Find a linear equation that relates Gallons sold to price. Use this equation to predict the number of gallons sold at a price of $1.20 per gallon.

List the ordered pair corresponding to the point. -B

Graph the equation. -

Indicate the quadrant in which the point belongs. -(-9, -12)

Indicate the quadrant in which the point belongs. -(9, 19)

Indicate whether the distinct lines, line 1 and line 2 are parallel, perpendicular, or neither. -12x - 4y = 48

By observing the vertical and horizontal change of the line between the two points indicated, determine the slope of the line. -

Graph the line with the given slope that goes through the given point. -
