Question

In a linear function $y=mx+b$, _______ represents the y-intercept and _____ represents the slope.

• A. $y,x$
• B. $b,m$
• C. $m,b$
• D. $m,x$

Answer 1

The correct option is B $b,m$

A linear function can be expressed in the form of $y=mx+b$, where $x$ and $y$ are the variables, m represents the rate of change or the slope, and b represents the $y$-intercept.
Slope: It can be defined as the rate of change. That means
$\frac{changeiny}{changeinx}$ or $\frac{rise}{run}$.
$y$-intercept: It can be defined as the point where the linear function or straight line is touching the $y$-axis.

So, option C is the correct answer.
