5.6 Standard Form of Linear Equations
5.6 Standard Form of a Linear Equation
y-intercept form - y=mx+b
Standard form- Ax + By =C (A, B, and C are
real numbers. A and B cannot be 0 and they
must be whole numbers.)
Examples:
Write y= 2/5x - 3 in standard form
1) multiply each side to
get rid of fractions
2)use distributive
property
3) move all the
variables to the left
y =
2
5
x-3
5.6 Standard Form of Linear Equations
Write y= 3x - 1 in standard form
Write an equation in standard form of the line
that passes through the given point with the
given slope. (-8, 3) m=2
Write the equations in standard form
m=0, b=4
m is undefined
there is no b
