Question

Y does y=mx+b?????????????????????????????????????

Answer 1

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

Explanation:

Step 1: To find out, suppose (x1, y1) and (x2, y2) are two

points on the graph of y = mx + b.

Step 2: Then y1 = mx1 + b and y2 = mx2 + b.

Step 3: Use algebra to simplify

y2 – y1

x2 – x1

Step 4: Or try Rise/Run.

Answer 2

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
