For the function y=4x−5, find y when x=3, and explain what the slope tells you about the relationship between x and y.

• y=7; The slope (4) tells you that for every increase of 1 in x, y increases by 4.

• y=12; The slope (4) tells you that for every increase of 1 in x, y decreases by 4.

• y=7; The slope (4) tells you that for every increase of 1 in x, y decreases by 4.

• y=12; The slope (4) tells you that for every increase of 1 in x, y increases by 4.
