Answer:
4*x+16*y-(12)=0
4x + 16y - 12 = 4 • (x + 4y - 3)
y=mx+b
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+4y-3 = 0 and calculate its properties.
Notice that when x = 0 the value of y is 3/4 so this line "cuts" the y axis at y= 0.75000
y-intercept = 3/4 = 0.75000
When y = 0 the value of x is 3/1 Our line therefore "cuts" the x axis at x= 3.00000
x-intercept = 3/1 = 3.00000
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 0.750 and for x=2.000, the value of y is 0.250. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 0.250 - 0.750 = -0.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -0.500/2.000 = -0.250
