How do you find B in the equation y MX B?
In the equation y = mx + b for a straight line, the number m is called the slope of the line. Let x = 0, then y = m • 0 + b, so y = b. The number b is the coordinate on the y-axis where the graph crosses the y-axis.
How do you solve for b in slope?
- Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
- Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
How do you find the B value?
Definition of the B-Value
The quadratic function is f(x) = a * x^2 + b * x + c. The b-value is the middle number, the number next to the x. The other letters, a and c, are also numbers like b. Each of these can be any number.
