Could someone please help me understand this algebra problem?

Question

Find the ordinate of a point on the line x+2y=6 if its abscissa is -4

Answer 1

In the line equation, x represent the abcissa and y the odinate:

simply replace x by -4 :

-4 + 2y = 6

then simplify :

2y = 6 + 4
2y = 10
y = 5

The ordinate is 5, and the point is (-4,5)

Good luck !

Answer 2

The question can be rephrased like this.

Find the Y-coordinate of the line x+2y=6 if its X-coordinate is -4.
(abscissa -> X Coordinate, ordinate -> Y Coordinate)

which means, if x = -4 and x+2y = 6 then what is y?

The solution to this can be found by substituting the value of x in the equation and rearranging to find the value of y.

=> -4 + 2y = 6
=> 2y = 6 + 4 (Solving this equation)
=> 2y = 10
=> y = 10/2
=> y = 5.


Thus ordinate of the line x+2y = 6 with abscissa -4 is 5.

Answer 3

The ordinate is the same as the y value. So what's being asked is to find the y value when the x value is -4.

I would solve the equation for y: y = 3 - x/2
Then put in (-4) for x and get y = 3 - (-4)/2 = 3 + 2 = 5

Answer 4

Which are the ordinate and the abscissa? Why can't they just say x value and y value?

The ordinate is the y value (see reference). So we put in -4 for x:

-4 + 2y = 6
2y = 10
y = 5

Answer 5

ordinate means y-co-ordinate
abscissa means x-co-ordinate
they have given u equation of line,
x co ordinate is given
find y co- ordinate
simple....
substitute x= -4
so its -4+2y=6
so 2y=10
hence y =5
