[Math Tutor]

What is the graph of the function: f(x) = ax + b.
How the graph changes according to the parameters a and b.

f(x) = ax + b ----linear graph

[leesajohnson]

For the given function f(x) = ax + b the graph will be "Linear graph".

What is the graph of the function: f(x) = ax + b.
How the graph changes according to the parameters a and b.

The graph of f(x)=ax+b is a straight line.

a (slope): determines the line's steepness.

The line rises (increases) if a>0.

The line falls (decreases) if a 0.

Greater |a| steeper line.

Where the line crosses the y-axis is indicated by the b (y-intercept).

The line rises when b is increased.

It slides down when b decreases.
