Find the distance between the points (-3, 2) and (4, -5)

Suppose a least-squares regression line is given by modifyingabove y with caret equals 4.302 x minus 3.293. what is the mean value of the response variable if xequals20?

What is the point-slope equation of a line with slope -5 that contains the point (6,3)

Ineed with angles and the measure of them i have abc a is 65 and b is (3x-10) and c is (2x) find the value of x
