Question

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

Answer 1

0,5 2,6 4,7

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

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.
