Exam 3: Linear Equations and Inequalities in Two Variables

Give the equation of the line with the given slope and y -intercept.

Michael starts a new job in sales next month. He will earn $800 per month plus a certain amount for each shirt he sells. The graph below shows the amount Michael will earn per month based on how many shirts he sells. Find the equation of this line where is the amount he earns for selling number of shirts.

Graph the line then name the slope and y -intercept by looking at the graph.

Graph the linear inequality.

For the equation complete the ordered pairs. ( 0, _____ ), ( _____ , -2 ), ( 1, _____ )

Graph the linear inequality.

Find the equation of the line with x -intercept 5 and y -intercept 2. Write your answer in slope intercept form.

Find the equation of the line.

Graph the linear inequality.

Find the equation of the line with x -intercept -5 and y -intercept -7. Write your answer in slope intercept form.

Find y if the line through (2, 2)and (4, y )has a slope of 2.

For the equation, complete the given table.

Give the coordinates of the point in the figure.

Find the slope and y -intercept for the line. Then write the equation of the line in slope-intercept form.

For the following problem, the slope and one point on a line are given. Use the point-slope form to find the equation of that line. (Write your answer in slope-intercept form.)

Graph the linear inequality.

Find the x - and y -intercepts for the equation. Then use the intercepts to graph the equation.

Graph the points (-2, 4)and (2, -4)and draw a straight line that passes through both of them. Does the graph of (- 1, 2)lie on this line?

Find the slope of the line through the pair of points (1, 2), (5, 0). Plot the pair of points, draw a line through them, and indicate the rise and run in the graph.

Find the slope and y -intercept for the line.
