Answer 1

hey cool to see another k12 student i could say x is zero and y is 2 becuase 10 + zero is

Answer 2

10

Answer 3

10?

Answer 4

ok

Answer 5

thats what i think could be wrong thought but thats how i would solve

Answer 6

so then what line is it?

Answer 7

looks like line a

Answer 8

Find the y and x intercepts
y intercept is y value when x = 0
2(0) + 5y = 10 solve this to get the y intercept
the x intercept is the other way around, the x value when y = 0
2x + 5(0) = 10 solve this to get the x intercept
these two points will show you what line is represented by the equation
Hope this helps! :)

Answer 9

to graph a line you need at least 2 points. the easiest to use are the intercepts.
when x = 0 what is y? point (0,y)
when y = 0 what is x? point (x, 0)
join the points
what line matches your line?
