Write in standard form an equation for the line with slope 1/3 through<br> the point (2,-2).
Alexxandr [17]

Answer:

x - 3y = 8.

Step-by-step explanation:

Use the point-slope form of the equation of a line:

y - y1 = m(x - x1)  where m = the slope and (x1, y1) is a point on the line.

So substituting the given values:

y - (-2) = 1/3(x - 2)

y + 2 = 1/3x - 2/3     Multiply through by 3:

3y + 6 = x - 2

x - 3y  =  6 + 2

x - 3y = 8  <---- Standard Form.

Change 3Y - 2X = -6 to the slope-intercept form of the equation of a line.
k0ka [10]

Answer:

y = 2/3x -2

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

3y -2x = -6

Solve for y

Add 2x to each side

3y = 2x-6

Divide by 3

3y/3 = 2x/3 -6/3

y = 2/3x -2
