Answer:

Solve 3x-2y-5 = 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 3x-2y-5 = 0 and calculate its properties

Solve using substitution-2x-y=-9. 5x-2y=18

Sunny_sXe [5.5K]

Equation 1) -2x-y=-9
Equation 2) 5x-2y=18

Multiply all of equation 1 by 2, so that both equations have (2y) in them.

1) 2(-2x-y=-9)

Simplify.

1) -4x-2y=-18
2) 5x-2y=18

Subtract equations with each other.

-9x=-36

Divide both sides by -9.

x=4

Plug in 4 for (x) into equation 1.

-2x-y=-9

-2(4)-y=-9

Simplify.

-8-y=-9

Add 8 to both sides.

-y=-1

Divide both sides by -1.

y=1

(4, 1)
