Ryanne is 14. Her brother’s age is three more than half her age. How old is her brother?

10

Step-by-step explanation:

14 / 2=7

7 + 3 = 10

10

Step-by-step explanation:

because

14/2+3=10 this is the explanation

because they could drop even lower..

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
