Write an equation of the line in slope intercept from given the following information, then sketch it's graph. 1. The point (5, -4) and slope -1/2 2. Points ( -3,4) and (5, 8) 3. Horizontal line passing through the point (2, -7) 4. The line perpendicular to x+y= 5 through the point (2, -3)

you're missing vital information, add to it so we can solve this problem for you.

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

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 )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
