Express in slope intercept form: -3x - 2y = 6

• y = 3x - 2

• y = -3/2x - 3

• y= 3/2x - 3

• y=-3/2x + 3

What is the slope?

• m= -2/3

• m=-1/4

Lee charges $3 for a basket and $2.50 for each pound of fruit picked at the orchard. Write an equation in y = mx + b form for the total cost of x pounds of fruit from the orchard.

• y = 3x + 2.5

• y = 2.50x + 3

• y = 2.50x 

• y = 3x + 2.50

Conner has $25,000 in his bank account. Every month he spends $1,500. He does not add money to the account.
 Write a linear model that shows how much money will be in the account after x months. 

• y=25000x-1500

• y=25000+1500

• y=1500x+25000

• y=-1500x+25000

Write the equation for the line in slope-intercept form.

• y= -1x+3

• y= 4x+3

• y=1/4x+3
