Equation of a Straight Line
1.1 Solve 2x+5y+15 = 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 2x+5y+15 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is -3/1 so this line "cuts" the y axis at y=-3.00000
y-intercept = -15/5 = -3
Calculate the X-Intercept :
When y = 0 the value of x is -15/2 Our line therefore "cuts" the x axis at x=-7.50000
x-intercept = -15/2 = -7.50000
Calculate the Slope :
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 -3.000 and for x=2.000, the value of y is -3.800. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -3.800 - (-3.000) = -0.800 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -0.800/2.000 = -0.400
Geometric figure: Straight Line
Slope = -0.800/2.000 = -0.400
x-intercept = -15/2 = -7.50000
y-intercept = -15/5 = -3

Equation of a Straight Line
1.1 Solve 3x+y+3 = 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

Calculate the Y-Intercept :
Notice that when x = 0 the value of y is -3/1 so this line "cuts" the y axis at y=-3.00000
y-intercept = -3/1 = -3.00000
Calculate the X-Intercept :
When y = 0 the value of x is -1/1 Our line therefore "cuts" the x axis at x=-1.00000
x-intercept = -3/3 = -1
Calculate the Slope :
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 -3.000 and for x=2.000, the value of y is -9.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -9.000 - (-3.000) = -6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -6.000/2.000 = -3.000

x = 0
y = - 3
Explicación paso a paso:
x = (- 3 - y) / 3
x = (- 15 - 5y) / 2
(- 3 - y)/3 = (-15 -5y)/2
(- 3 - y)(2) = (-15 -5y)(3)
-6 -2y = -45 - 15y
39 = - 13y
y = - 3
3x + (- 3) = -3
3x = 0
x = 0
