Algebra 2 Math question Grade 11

Can anyone please help me with this question? Soon as possible!


In a linear equation of the form y = mx + b, as b increases, what happens to the line?

Which of these choices is the correct answer?


The line moves up.

The line gets steeper.

The line moves down.

The line moves to the right

None of these describes how the line changes.

Answer 1

Answer: A) The line moves up

The b determines the y intercept

For example, y = 2x+5 has a y intercept of 5

Another example, y = 2x+6 has y intercept 6

The value of b has gone up by 1, so the graph shifts up by 1.

See the diagram below.

The slope stays the same, so both lines are parallel.
