Peter has 100 dollars. his mom gives him x dollars more. write an expression to represent the situation.

100+x

Step-by-step explanation:

Peter starts out with 100 dollars and then gets X more meaning we have to add X to what he originally had and that looks like this 100+x

I hope this helps and please don't hesitate to ask if there is anything still unclear!

x + 100

we know he has 100, and the unknown amount is x. since he has 100 and an undefined amount, you just add them together as you would with 2 defined amounts

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
