Slope of a parallel line would be 3/4.
The slope of a perpendicular line would be -4/3
Put this equation in the slope intercept form of al line
6x -8y = -7 Subtract 6x from both sides of the equation.
-8y = -6x - 7 Divide all the way through by -8
y = x - - Clean it upy = x + In this equation. The slope is Any equation with a slope of is parallel to this line and any equation that has a slope of if perpendicular to this line. Perpendicular slopes are the negative reciprocals.

answer: 33 ( approx)
since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )
here given table is,
price ($), x : 18 23 25 29 30 33
pairs sold, y : 16 13 10 8 6 2
so, , , ,
thus, slop of the given line is,
⇒ ≈ 33
