CCSS.HSF.IF.A.1

the linear function y = 5x + 4 and the linear function with a slope of 4 and a y-intercept of 8. 

Which of these statements is correct?

• Both functions have the same y intercept

• Both functions have the same slope

• the function y = 5x + 4 has the greater rate of change

• the function y = 5x + 4 has the lesser rate of change
