Y m x b where m is the slope of the line and b is the y-intercept. If you a point that a line passes through and its slope this page will show you how to find the equation of the line.

Y 2 x3 y 2 x 3 y 2x 6 y 2 x 6.

Math help y=mx+b. You will need to get assistance from your school if you are having problems entering the answers into your online assignment. B is the point value of where the line intercepts the y axis called the y intercept. X how far along.

Rewrite into y mx b y m x b format. The y-intercept of this line is the value of y at the point where the line crosses the y axis. From 0b use the slope m to find the next point.

Mxb y m x b y. From the y-intercept point use the slope to find a. This is my favorite way to write the equation of a line and I hope that this video is helpful for youMy.

A function whose graph is a straight line is called a linear function. M is in the form of ab where a is the change in y and. Now were in the right format and we can easily plot it.

Y mx b or y mx c in the UK see below What does it stand for. If you have more than two points then calculate y for x in each xy point given in terms of a and b and subtract the y for that point. Multiply the 2 over the parenthesis.

The point 0b is on the graph. In the equation y mx b b is the point where the line intersects the y axis and m denotes the slope of the line. To graph the equation of a line written in slope-intercept ymxb form start by plotting the y-intercept which is the b value.

Math Lesson on the Slope-Intercept form of a line. The equation is in standard form. M x y b.

The slope or gradient of a line describes how steep a line is. Phone support is available Monday-Friday 900AM-1000PM ET. Swap sides so that all variable terms are on the left hand side.

Y mx b In this equation x and y are still the variables. Y mx b is the equation for a straight line. Y mx b is the slope intercept form of writing the equation of a straight line.

I suggest you start by subtracting the first equation from the second. The equation of any straight line called a linear equation can be written as. Solve those two equations for a and b.

Solve for b ymxb. That eliminates b leaving an equation to solve for a. M is the value of the slope of the line.

Y mx b y m x b. Rewrite the equation as mxb y m x b y. Sometimes you will see the x and y on the same side of the equation or a term that multiplies y like this nasty example.

For any equation in the form ymxb b is the y intercept. The equation of a line is typically written as ymxb where m is the slope and b is the y-intercept. We are here to assist you with your math questions.

B y mx b y - m x. How do you find m and b. The equation is in standard form.

Subtract mx m x from both sides of the equation. Free Pre-Algebra Algebra Trigonometry Calculus Geometry Statistics and Chemistry calculators step-by-step. M Slope or Gradient how steep the line is b value of y when x0.

Three worked out examples showing how we can start with a linear equation that is not in the form ymxb and rewrite it so that we can quickly graph it using slope-intercept. The equation can be written in the slope-intercept form of equation y mx b where x and y are used to represent independent and dependent variables respectively and m 0. The slope intercept form uses the following equation.

Just see where the line crosses the Y axis. M x b y. The coefficients are m and b.

X is the value where the line intercepts the x axis. It can have either a positive or a negative 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.

Y when x0 see Y Intercept y how far up.
