Write (y - 4) = -1/2(x - 6) in slope-intercept form and in general form.

Answer:

y = - [tex]\frac{1}{2}[/tex] x + 7 , x + 2y = 14

Step-by-step explanation:

The equation of a line in slope- intercept form is

• y = mx + c ( m is the slope and c the y- intercept )

given the line with equation

y - 4 = - [tex]\frac{1}{2}[/tex] (x - 6 ) ← distribute the parenthesis by - [tex]\frac{1}{2}[/tex]

y - 4 = - [tex]\frac{1}{2}[/tex] x + 3 ( add 4 to both sides )

y = - [tex]\frac{1}{2}[/tex] x + 7 ← in slope- intercept form

The equation of a line in general form is

• Ax + By + C = 0 ( where A and B are both non zero )

From the slope- intercept form

y = - [tex]\frac{1}{2}[/tex] x + 7 ( multiply through by 2 )

2y = - x + 14 ( add x to both sides )

x + 2y = 14 ( subtract 14 from both sides )

x + 2y - 14 = 0 ← in general form
