Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 1/5*x-1/5*y-(2/5)=0

Step 1 :

2 Simplify — 5

Equation at the end of step 1 :

1 1 2 ((—•x)-(—•y))-— = 0 5 5 5

Step 2 :

1 Simplify — 5

Equation at the end of step 2 :

1 1 2 ((— • x) - (— • y)) - — = 0 5 5 5

Step 3 :

1 Simplify — 5

Equation at the end of step 3 :

1 y 2 ((— • x) - —) - — = 0 5 5 5

Step 4 :

Adding fractions which have a common denominator :

4.1 Adding fractions which have a common denominatorCombine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

x - (y) x - y ——————— = ————— 5 5

Equation at the end of step 4 :

(x - y) 2 ——————— - — = 0 5 5

Step 5 :

Adding fractions which have a common denominator :

5.1 Adding fractions which have a common denominatorCombine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(x-y) - (2) x - y - 2 ——————————— = ————————— 5 5

Equation at the end of step 5 :

x - y - 2 ————————— = 0 5

Step 6 :

When a fraction equals zero :

6.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.Here's how:

x-y-2 ————— • 5 = 0 • 5 5

Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.The equation now takes the shape : x-y-2 = 0

Equation of a Straight Line

6.2 Solve x-y-2 = 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 goesx tells us how far alongm is the Slope or Gradient i.e. how steep the line isb is the Y-intercept i.e. where the line crosses the Y axisThe X and Y intercepts and the Slope are called the line properties. We shall now graph the line x-y-2 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 2/-1 so this line "cuts" the y axis at y=-2.00000

y-intercept = 2/-1 = -2.00000

Calculate the X-Intercept :

When y = 0 the value of x is 2/1 Our line therefore "cuts" the x axis at x= 2.00000

x-intercept = 2/1 = 2.00000

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 -2.000 and for x=2.000, the value of y is 0.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 0.000 - (-2.000) = 2.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 1

Geometric figure: Straight Line

1. Slope = 1
2. x-intercept = 2/1 = 2.00000
3. y-intercept = 2/-1 = -2.00000
