How to find general form from slope intercept form. One way to represent the equation of a line is in its slope intercept form y mx b where m represents the slope of the line and b is the y coordinate of the y intersection. Y mx b. We can use algebra to convert the general form into the slope intercept form.
The general form of the equation of a straight line is. Once we know the slope intercept form we can read off the number in front of the x the m to find the slope. If the slope of a line is undefined then the line is a vertical line so it cannot be written in slope intercept form but it can be written in the form.
Y a b x c b which is the required slope intercept form y mx b of the general form of line ax by c 0 where m a b b c b. In general the slope intercept form assumes the formula. The slope intercept form calculator will teach you how to find the equation of a line from any two points that this line passes through.
Divide both sides by b. The general form is not always the most useful form and you may prefer to use. We can compare this equation with the slope intercept form of a linear equation.
M is the slope lesson on slope mnemonic. The slope intercept form of the equation of a straight line. A real example of finding the slope from a linear equation in general form.
For example the equation y 2x 3 has a slope of 2 and has a y intersection at 0 3 as illustrated. This is called slope intercept form because m is equal to the slope of the line and b is the value of y when x 0 which makes it the y intercept. I hope that this was helpful.
Free slope intercept form calculator find the slope intercept form of a line given two points a function or the intercept step by step this website uses cookies to ensure you get the best experience. It will help you to find the coefficients of slope and y intercept as well as the x intercept using the slope intercept formulas. Xa where a is a constant.
M means move b is the y intercept lesson on the y intercept mnemonic. Read more about converting a linear equation in general form to slope intercept form. The standard form of such an equation is ax by c 0 or ax by c.
Example if the line has an undefined slope and passes through the point 23 then the equation of the line is x2. Ax by c 0. If b 0 then from the given equation we get by ax c subtracting ax from both sides y abx cb dividing both sides by b 0.
The y intercept is given by cb. Subtract c from both sides. B means where the line begins.
When you rearrange this equation to get y by itself on the left side it takes the form y mx b. It is the m in the slope intercept form that tells you the slope. The slope is given by ab.
