Question

in the equation $y = mx + b$, what is $b$?
a. coefficient
b. solution
c. slope
d. y-intercept

Explanation:

In the linear equation \(y = mx + b\), \(b\) represents the y-intercept, which is the point where the line crosses the y-axis (when \(x = 0\)). The other options are incorrect: \(m\) is the slope, a coefficient is a constant multiplying a variable (like \(m\) for \(x\)), and a solution is a pair \((x,y)\) satisfying the equation.

Answer:

d. y-intercept
