Linear function

Question

A linear function has a slope of 7, and when x is 3, the value for y is 22. Use a graph or a table to figure out the equation of the function. Show your work.

Answer 1

or, disobeying instructions (setting the goal as SOLVE by any valid known method):

 

m = 7

 

y=mx+b

22 = 7(3) + b  means b=1

 

y = 7x + 1
