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.

Fill in the missing values for the equation below

Firlakuza [10]

Look where the line is touching on the y-axis and that will be your y-value. From there or somewhere on the line use rise over run (rise/run, do not divide). Count how many times it goes up and then count how many times it goes left or right. Make sure to look where the line is going, up or down slanted. If the line is going down, but slanted it will be a negative slope; line going up and slanted is positive.
