Construction workers are doing a building project using floor plans
that have a scale of 1 cm to 2 m.
On the floor plans, a corridor is
shown with a length of 9 cm. How
many meters long will the actual
corridor be?

it is x=-4

step-by-step explanation:

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

but there’s no any figure there!
