How to find standard form. A shouldnt be negative a and b shouldnt both be zero and a b and c should be integers. Ax by c. The standard form is just another way to write this equation and is defined as ax by c where a b and c are real numbers and a and b are both not zero see note.
The standard form for writing down a linear equation is. You are probably already familiar with the slope intercept form of a line y mx b. Where a b and c are real numbers and a 0.
Ax by c. Using vertex form to derive standard form. Y ax h 2 k.
Y ax 2 2ahx ah 2 k. The standard form of a linear equation is ax by c where a b and c can be any number. Why standard form is useful standard form is great for finding the x and y intercepts of a graph that is the point where the graph crosses the x axis and the point where it crosses the y axis.
Standard form of a linear equation. This gives us the standard form. Y ax 2 2xh h 2 k.
The coefficient of the x term should be a positive integer value so we multiply the entire equation by an integer value that will make the coefficient positive as well as all of the coefficeints integers. Write the vertex form of a quadratic function. 4000 in standard form 4000 x 10 3.
The x intercept frac c a frac 6 3 2. Converting 4000 to standard form it would be given as 4 times 103 similarly 8500 would be given as 85 times 103 now let us multiply both these standard forms to get the final result 4 times 85 times 103 times 103 34 times 106 some other quick calculations chart for standard form. The standard form of a quadratic function is y ax 2 bx c.
