Lucina is given the equation y+8=−14(x+4) and asked to rewrite the equation in slope-intercept form.

her work is outlined below:

y+8=−14(x+4)

step a: y+8=−14x+4

step b: y+8−8=−14x+4−8

step c: y=−14x−4

at which step, if any, did lucina make a mistake?

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

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
