Ling tried to solve an equation step by step. \qquad\begin{aligned} -2q+11&=-32 \\ -2q&=-43&\green{\text{Step } 1} \\ q&=21.5&\blue{\text{Step } 2} \end{aligned} −2q+11 −2q q =−32 =−43 =21.5 Step 1 Step 2 Find Ling's mistake. Choose 1 Choose 1 (Choice A) A \green{\text{Step }1}Step 1start color #28ae7b, start text, S, t, e, p, space, end text, 1, end color #28ae7b (Choice B) B \blue{\text{Step }2}Step 2start color #6495ed, start text, S, t, e, p, space, end text, 2, end color #6495ed (Choice C) C Ling did not make a mistake.

the answer is c : long didn’t make a mistake

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

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.
