Exam 4: Linear Systems

Graph: 3x + 4y = 12

Find the slope and y-intercept: 3y - 5 = 2(x - 2)

Graph: 5x + 4y = 20

Graph: 2x - 4y = 10

Find the slope and y-intercept: 4 - y = 2x

Solve the equation for x and find slope and x-intercept of 2x + 4y = 8

It takes a car 10 seconds to increase its speed from from 60 k/hr to 90 k/hr.What is the rate of acceleration (slope)in k/hr/sec?

Two brothers decide to invest in a vacant lot which cost $51 000.The first brother contributes $1000 more than one-quarter of what the second brother contributes.How much does each brother contribute?

Solve the system graphically.

Find the slope and y-intercept: 1.5x + 3y = 2.4

Graph: y = 8

Find the slope and y-intercept: 2x - y = 8

Twice the larger number is greater than three times the smaller number by 19.The sum of the larger number plus one-third of the smaller number is 26.Find the two numbers.

A tavern holds 50 seats.Two types of seats are available the Friday night jazz festival: stage and dining.The cost of a stage seat is $15.00 and the cost of a dining seat is $5.00.If all 50 seats are sold the tavern would collect $400.00.How many of each type of seat is available?
