What is the B value in slope-intercept form?

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). This useful form of the line equation is sensibly named the “slope-intercept form”.

Where do you start your graph in slope-intercept?

To graph the equation of a line written in slope-intercept (y=mx+b) form, start by plotting the y-intercept, which is the b value. The y-intercept is where the line will cross the y-axis, so count up or down on the y-axis the number of units indicated by the b value.

What does B represent in the equation of a line in the form y mx b quizlet?

The slope-intercept form of a linear equation is y=mx+b, where m is the slope and b is the y-intercept.

How do you graph a line using slope and y intercept?

Graphing a Line Using the Slope and Y-Intercept

  1. Find the y-intercept = b of the equation y = mx + b.
  2. Plot the y-intercept. The point will be (0, b).
  3. Find the slope=m of the equation y = mx + b.
  4. Make a single step, using the rise and run from the slope.
  5. Connect those two points with your line.

How do you graph a line from an equation?

To graph an equation using the slope and y-intercept, 1) Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). 2) Next, plot the y-intercept. 3) From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

Steps for Graphing a Line With a Given Slope

  1. Plot a point on the y-axis.
  2. Look at the numerator of the slope.
  3. Look at the denominator of the slope.
  4. Plot your point.
  5. Repeat the above steps from your second point to plot a third point if you wish.
  6. Draw a straight line through your points.

Which graph can be represented by the equation y MX B?

Every straight line can be represented by an equation: y = mx + b. The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y.

What does the B stand for in Y MX B?

y intercept of
m is the slope of the line (change in y/change in x) and b is the y intercept of the line (where the line crosses the y axis).
