Step by Step Solution



Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 1-(a-b)*2-((1+a-b))=0

Step 1 :

Equation at the over of step 1 :

(1 - 2 • (a - b)) - (a - b + 1) = 0

Step 2 :

Step 3 :

Pulling out lượt thích terms :3.1 Pull out like factors:3b - 3a=-3•(a - b)

Equation at the kết thúc of step 3 :

-3 • (a - b) = 0

Step 4 :

Equations which are never true: 4.1Solve:-3=0This equation has no solution. A a non-zero constant never equals zero.

Equation of a Straight Line 4.2Solvea-b=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 & "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 và the Slope are called the line properties. We shall now graph the line a-b = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :Notice that when a = 0 the value of b is 0/-1 so this line "cuts" the b axis at b=-0.00000

b-intercept = 0/-1 = -0.00000 Calculate the X-Intercept :When b = 0 the value of a is 0/1 Our line therefore "cuts" the a axis at a= 0.00000

a-intercept = 0/1 = 0.00000 Calculate the Slope :Slope is defined as the change in b divided by the change in a. We cảnh báo that for a=0, the value of b is 0.000 & for a=2.000, the value of b is 2.000.

So, for a change of 2.000 in a (The change in a is sometimes referred khổng lồ as "RUN") we get a change of 2.000 - 0.000 = 2 ngàn in b. (The change in b is sometimes referred khổng lồ as "RISE" và the Slope is m = RISE / RUN)

Slope = 1

Geometric figure: Straight Line

Slope = 1 a-intercept = 0/1 = 0.00000 b-intercept = 0/-1 = -0.00000
