Modeling Equation in Slope Intercept Form

MODELING: The table shows the cost y (in dollars) of x pounds of sunflower seeds. Write a linear function that represents the cost y of x pounds of seeds. Interpret the slope.

• The slope represents the cost per pound of sunflower seeds.

• The slope represents the pounds per cost of sunflower seeds.

Linear Modeling:
A local donut shop charged $6.50 for a dozen and provided a coupon in the newspaper for $1.50 off an order. Since the donut shop has gained popularity they have changed their coupon which now provides a discount of only half their original coupon's value. What is the equation that represents the value of a customer's order who uses the new coupon with their order?

• y = 6.50x - 0.75

• y = 6.50x + 0.75

• y = 6.50x - 1.50 - 0.75

• y = 5x - 0.75

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

• y = (-2/3)x + 4

• y = (2/3)x + 4

• y = (3/2)x + 4

• y = (-3/2)x + 4

Write the equation of the line.

• y=-3x-4

• y=-4x-3

• y=(-3/4)x-3

• y=(-4/3)x-3

Write an equation of the line in slope-intercept form.

Give the equation for the graph

• y = 5x - 3

• y = 4x + 2

• y =-2x + 5

• y = - 2x + 4

How do you change y-4=3(x+3) into slope-intercept form?

• y=23x-1/23

• y=3x+13

• y-7x=9

• y=13-3x
