Linear Equations Systems

• y=-5x+5

• y=-x+5

• y=x+1

• y=-x+1

Convert the standard form equation into slope-intercept form.
4x - 3y = 15

• y = (4/3)x - 5

• y = ⅔x - 5

• x = ¾

• y = 27, 239, 430

Write in slope intercept form
5x - 3y = -9

• y = (5/3)x - 3

• y = (5/3)x + 9

• y = (5/3)x + 3

• y = (3/5)x + 3

Bob has $150 in his savings account and saves $40 per month.  Which equation represents the amount Bob has in his account after x months?

• y = 150 + 40

• y = 40x + 150

• y = 150x + 40

How much water was in the tank to start?

• 0 gallons

• 2 gallons

• 4 gallons

• 5 gallons

What is the rate the tank is draining, in gallons per second?

• -1/2 (1 gallon every 2 seconds)

• -1/3 (1 gallon every 3 seconds)

• -1/4 (1 gallon every 4 seconds)

• -1/5 (1 gallon every 5 seconds)

Solve for x and y
3x + 2y = 16
7x + y = 19

• (-2,5)

• (-2,-5)

• (2,-5)

• (2,5)

Solve using substitution.
x - 2y = 2
3x + 4y = 3

• (1.4, -0.3)
