Slope-intercept form: y=mx+b
Standard form: Ax+By=C
Ax+By=C --> By=-Ax+C --> y=-Ax/B+C/B
Well they might need a little more help than just formulas... here is an example
Standard form has
ax + by = c, where a, b, and c are integers.
Slope-intercept form has
y = mx + b
To convert slope-intercept form to standard form, subtract mx from both sides of the equation.
-mx + y = b
If m is a fraction, multiply the equation by its denominator.
Example
y = 2/3x + 6 (slope-intercept form)
-2/3x + y = 6 (after the subtraction
of 2/3x)
-2x + 3y = 18 (standard form, after multiplication by 3)
It is: 2.63*106
Solve the equation for ' y '.
y = mx + b, just subtract mx to both sides -mx + y = b. If the slope is a fraction, it is nice to eliminate the denominator first, so go and multiply each term at both sides by the denominator. If both, the slope and the constant, are fractions, multiply each term at both sides by their least common denominator.
The equation of the line is of the form y = 3x + c where c is a constant. The point (4,9) is on the line, so substituting x=4, y=9 in the equation, 9 = 3*4 + c = 12 + c so c = -3 So the equation of the line is y = 3x - 3
In the equation y x-5 2 plus 16 the standard form of the equation is 13. You find the answer to this by finding the value of X.
You can convert standard form to factored form by using a factoring tree to convert to the long-form factored format. You can also work backwards to convert from factored to standard form.
That already is in standard form.
You multiply the factors.
y = 2x + 1.
Do nothing! Standard form and scientific notation are the same.
