Brianna went on a trip to the art museum and sketched a scale drawing of a rectangular wall mural. she used a scale factor of 0.2. the sketch was 12 inches wide and 18 inches long. what was the length of the mural?
3.6 inches
18.2 inches
60 inches
90 inches

The length of the mural was 90 inches.

Step-by-step explanation:

Brianna went on a trip to the art museum and sketched a scale drawing of a rectangular wall mural.

She used a scale factor of 0.2 =

the sketch was 18 inches long.

Let the length of the mural be x

the actual length of the mural = x = 18

                                             x   = 18 × 5

                                              x  = 90

The length of the mural was 90 inches.

i think asking google will you get the answer to that question

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
