what is b in the slope formula Equation of a Straight Line The equation of a straight line is usually written this way y mx b or y mx c in the UK see below What does it stand for y how far up x how far along m Slope or Gradient how steep the line is b value of y when x 0 How do we find m and b
Y mx b is the slope intercept form of a staight line In the equation y mx b for a straight line m is called the slope of the line and b is the y intercept of a line y mx b where y how far up or down is the line x how far along is the line b the value of y when x 0 and m how steep the line is The slope formula refers to the formula used to calculate the steepness of a line and determines how much it s inclined To calculate the slope of the lines the x and y coordinates of the points lying on the line can be used In other words it is the ratio of the change in the y axis to the change in the x axis Slope Formula

The slope intercept form of a linear equation is where one side contains just y So it will look like y mx b where m and b are numbers This form of the equation is very useful The coefficient of x the m value is the slope of the line And the constant the b value is the y intercept at 0 b B b represents the y y intercept of the line which is the point where the line intersects the y y axis x x value represents the x x coordinate of any point on the line y y value represents the y y coordinate of any point on the line
The form y mx b means slope m and y intercept b similarly the form y mx a means slope m and y intercept a The form y m x a is essentially different from the other two forms and means slope m and x intercept instead of y intercept a Y 1 1 x 2 4 y 2 7 Explain 2 1 4 7 x 1 y 1 x 2 y 2 x 1 x 1 st y 1 y 1 st x 2 x 2 nd y 2 y 2 nd Step 2 Plug in these values to the slope formula to find the slope Slope y 2 y 1 x 2 x 1 7 1 4 2 6 2 3 Step 3 Gut check

The slope of a line m in the equation for a line of the form y mx b can be found using the slope formula as long as at least two points on the line are known It can be written as follows Example Given two points 1 3 and 4 7 Use the slope intercept formula to find the slope m y y x x 3 1 2 1 2 1 2 Calculate the y intercept You can also use x and y instead of x and y here b y m x 1 2 1 1 Put all these values together to construct the slope intercept form of a linear equation y 2x 1
