Step-by-step explanation:

Convert the equation to the slope-intercept form (y = mx + b):

[tex]-x-2y=-10[/tex]             add x to both sides

[tex]-2y=x-10[/tex]          divide both sides by (-2)

[tex]y=-\dfrac{1}{2}x+5[/tex]

Choose any three values of x ​​and calculate the values od y:

for x = 0

[tex]y=-\dfrac{1}{2}(0)+5=0+5=5\to(0,\ 5)[/tex]

for x = 4

[tex]y=-\dfrac{1}{2}(4)+5=-2+5=3\to(4,\ 3)[/tex]

for x = 10

[tex]y=-\dfrac{1}{2}(10)+5=-5+5=0\to(10,\ 0)[/tex]
