Kira worked 87/100 of the problems on her math test in the first hour.
after the second hour, she had worked 97/100 of the problems.

what fraction of the problems did she work in the second hour?

She had worked 10/100 more problems in the second hour

Hope this helps :)

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
