17more than a number is 85

Well a number is (x) {unknown}

Its 17 more

So x+17=85

Now solve

subtract 17 on both sides

x=68

So the number is 68

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
