Answer: y-intercept = 18/-2 = simplified: 9/-1 = decimal form: -9.00000
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*x-8*y-(72)=0
Solve x-2y-18 = 0
"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-2y-18 = 0 and calculate its properties
Notice that when x = 0 the value of y is 9/-1 so this line "cuts" the y axis at y=-9.00000
y-intercept = 18/-2 = 9/-1 = -9.00000
