Use the slope formula (m = Y2 - Y1
) to find the slope of a line given two points.
X2 – X1
-1
(-7, -3) and (-6, -4)
x
1
(1, 6) and (-3,0)
1.5
(7, 2) and (0, -5)

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Rose drew a regression line for this paired data set. her line passed through (1, 2) and (3, 5) . what is the equation of rose's regression line?
