which points are on the graph of the equation -3x+6y+5=(-7)

Question

Answer 1

This is the equation of a line.  To find points on the line,

plug in a value for one variable and find the corresponding

value of the other.  The most common method is to put the

equation in the slope intercept form of y = mx + b.  Then

plug in values for x and solve for y.

 

-3x + 6y + 5 = -7

6y + 5 = 3x - 7

6y = 3x - 12

y = (1/2)x - 2

 

x        (1/2)x-2

------------------

-2         -3

0          -2

2          -1

 

and so forth.

 

You can plot as many points as desired, but two is enough to graph the line.
