Based on the residual plot shown, is a linear model appropriate for comparing tree age to basal area?
A forest management agency collects measurements
from beech trees in a public park. The age of many of
the trees is known, and the basal area—the area of land
occupied by the trunks of the trees-is also measured. A
least-squares equation that compares the basal area to
the age of each tree is given by area = 0.439(age) +6.226.

The triangles are similar. what is the value of x? show your work.

Which equation represents the line that passes through the points and (4, 10) and (2, 7)? y = 3/2x - 11y = 3/2x +4y = - 3/2x + 19y = - 3/2x + 16
