Answer:
hello dear here is your answer
Step-by-step explanation:
Geometric figure: Straight Line
Slope = 0.889/2.000 = 0.444
x-intercept = 20/4 = 5
y-intercept = 20/-9 = -2.22222
Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-9y + 4x - 20 = -1 • (9y - 4x + 20)
Equation at the end of step 1 :
Step 2 :
Equation of a Straight Line
2.1 Solve -9y+4x-20 = 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 -9y+4x-20 = 0 and calculate its properties
Answer:
x=5
y=0
