Respuesta :
x=3y+18
Geometric figure: Straight Line
Slope = 0.667/2.000 = 0.333
x-intercept = 18/1 = 18.00000
y-intercept = 18/-3 = 6/-1 = -6.00000
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
x-(3*y+18)=0

Step 1 :
Equation of a Straight Line
1.1 Solve x-3y-18 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line x-3y-18 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 6/-1 so this line "cuts" the y axis at y=-6.00000
y-intercept = 18/-3 = 6/-1 = -6.00000
Calculate the X-Intercept :
When y = 0 the value of x is 18/1 Our line therefore "cuts" the x axis at x=18.00000
x-intercept = 18/1 = 18.00000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -6.000 and for x=2.000, the value of y is -5.333. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -5.333 - (-6.000) = 0.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 0.667/2.000 = 0.333
Geometric figure: Straight Line
Slope = 0.667/2.000 = 0.333
x-intercept = 18/1 = 18.00000
y-intercept = 18/-3 = 6/-1 = -6.00000
hope this helped:)))
