Exam 3: Thinking Linearly

Complete the table of points for the equation 8x - 2y = 6. (If answers are decimals, round to one decimal place.)

Sketch the graph of 2x = 11.

Find the slope and y-intercept of the equation. y + 12 = -2x

The price per share of stock (in dollars)over a period of 5 days is shown in the graph. What was the loss between day 3 and day 4?

Find the slope of the line that passes through the points (2.4, 0.2)and (1.6, 1.2)

Find the slope and y-intercept, and use them to sketch the graph.

Solve the system using the substitution method.

Solve the system using the substitution method.

Sketch the graph of the equation. 4x + y = -4

Sketch the graph of the equation.

Determine the slope by using the slope formula and any two points on the line.

Which table of points is correct for the equation -y= 36 - 9x?

Solve the system using the substitution method.

x varies directly as p . If x=14 when p=2 , find x when p is 7 .

My spouse was recently in Mexico, and I had to determine the cheapest way to call. AT&T has an international wireless plan called World Connect with a monthly fee of $3.99, and then my calls to a Mexican landline are $0.09 per minute. Without this plan, I would pay no monthly fee and $0.49 per minute. a. Write equations for the cost C of each option. I'm using the letter _______________ to represent the variable quantity __________. b. Solve the system of equations you wrote in part a to find the number of minutes for which the two options would cost the same. (Round to the nearest whole minute.)When would it make sense to pay for the World Connect plan?

Plot each of the following points on the same set of axes.

Find the slope and y-intercept, and use them to sketch the graph. y = -4x + 21

Write the linear equation in slope-intercept form. 8x - y = 24

Complete the table of poins for the equation Then use those points skecth the graph.

The price per share of stock (in dollars)over a period of 5 days is shown in the graph. What was the gain between day 4 and day 5?
