5x+4y=20 is technically the equation of a line.
A more familiar representation of the line is in "y equals" notation. This simply means that the y variable has been isolated (this notation is usually required for graphing calculators). To get the equation in y equals notation, simply isolate the y variable:
5x+4y=20
4y=(-5)x+20
y=((-5)x+20)/4
20 = 400
20 plus 20 equals 4020 plus 20 = 40
Yes.
Is the equation of a straight line with slope 2 and an intercept of (0,20).
The two equations represent the same straight line.
Slope-line form is: y = -4(x/5 + 1)
205
-15 plus 20 is 5.
1985 plus 20 is 2005
Negative 15 plus positive 20 equals 20 minus 15, which equals 5.
803 + 20 = 823823 - 100 = 723803 plus 20 minus 100 equals 723.
Of course!
