linear equation: y= 3.5x + 20

height at 20: 90in


Explanation-

linear equation:

x represents the number of years
y represents the height in inches

we’ll have the points
(0,20) height at birth
(8, 48) height at 8th birthday

to find slope you would do

m= (48-20)/(8-0)
= 3.5 inches/year

b would be 20

so y= mx + b would give you

y=3.5x + 20

if you add 20 into that equation you’d get

y= 3.5(20) + 20 = 90inch

y=90
