Question

The graph shows the total cost y for x bags of popcorn sold. What is the slope of the line?

Select one:

16

4

2

8

Answer 1

4

Explanation:

Slope (m) =

ΔY

ΔX

=

4

1

= 4

θ =

arctan( ΔY )

ΔX

= 75.963756532074°

ΔX = 4 – 2 = 2

ΔY = 16 – 8 = 8

Distance (d) = √ΔX2 + ΔY2 = √68 = 8.2462112512353

Equation of the line:

y = 4x

When x=0, y = 0

When y=0, x = 0

Answer 2

the slope should be 4/2
