The equation y = 2.34x + 6.78 models the approximate height of a tree in inches after x weeks. Which statements are true about the linear model?

Select 2 answer choices that apply.

• The tree grows a total of 2.34 inches.

• The tree grows about 6.78 inches each week.

• The tree grows about 2.34 inches each week.

• The initial height of the tree is 6.78 inches.

• The initial height of the tree is 2.34 inches.

Which of these represents slope-intercept form?

• y - y₁ = m(x-x₁)

• Ax + By = C

• y = mx + b

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

• y = - 1/4x - 3

• y = 1/3x + 3

• y = - 1/4x + 2

• y = 1/3x -3
