Question

Graph the linear equations in three points: -x-2y=-10

Answer 1

Answer:

0,5  2,6  4,7  

Step-by-step explanation:

You have to solve the equation by keeping y on its own. The equation is

y=-1/2x-5

Coordinates are:

0,5  2,6  4,7  

Answer 2

Answer:

Step-by-step explanation:

Rewrite -x-2y= -10 as  -2y= x - 10 and then as y = (-1/2)x + 5.

Then choose any 3 x values and find the corresponding y values using this formula.  For example:

 x     y = (-1/2)x + 5              (x, y)

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

 0                   5                    (0, 5)

-4       (-1/2)(-4) + 5 = 7         (-4, 7)

  6      (-1/2)(6) + 5 = 2          (6, 2)

Plot these three points and then draw a line through them.
