Use the triangle shown on the right to answer the question. Which equation can you use to solve for a?

its 4 because 2 times 2 is 4, if you double the number two you get four

is there supposed to be a diagram or a graph for this one? ?

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
