Exam 4: Linear Systems

Solve graphically: 4y = -5x and x = -6

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

Solve graphically: 0.2y = 0.1x + 2 and 0.3x + 0.2y = 2.4

Graph: 5x + 4y = 20

My son and daughter were born two years apart. 9 years ago, my son was twice the age of my daughter. What are their ages now?

Solve the system of equations: - = 6 3x + 4y = 12

Solve and find the value of a, given 3a + 4b = 20 and 2a + b = 15

Graph: 2x - 4y = 10

Solve graphically: 4x + 3y = 12 and 3x - 4y = -24

Solve graphically: 2y = x + 200 and 3x + 2y = 240

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

Solve and find the value of y, given 3x + 5y = 5 and x + 2y = 1

Find the slope of the line: 2y = 4(y + 2)

Find the slope and y-intercept: 10 - y = 8x

Graph: 3x - 2y = 18

Graph: 7x + 4y = 0

Solve graphically: 2x = -5y and 3x + y = 9

The Oak Store has been producing 4640 chairs a day working two shifts. The second shift has produced 120 chairs fewer than four-thirds of the number of chairs produced by the first shift. Determine the number of chairs each shift has produced.

Solve graphically: x - y = 4 and x + y = 6

Graph: x = 7
