Find two numbers with a sum of 14 and a difference of 4:

First number --> x

Second number --> y

x + y = 14 --> x = 14 - y

x - y = 4

so

14 - y - y = 4

14 - 2y = 4

2y = 10

y = 5

so

x = 14 -5

x = 9

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
