A worker uses 560 inches of steel wire to make 350 springs of the same size. At this rate how many inches of steel wire are needed to make 1 spring?

1.5 inches of steel

Step-by-step explanation:

450/300

=1.5 in.

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
