Question

graph the equation using the x- and y-intercepts
x/3-y/5=1

Answer 1

do u know how to find the intercepts ?

Answer 2

easiest to solve the equation for y first?

Answer 3

in this case, we can use the intercept form of equation of line:
x/a+y/b=1
where a is x-intercept, b is y-intercept
so now compare your equation with x/a+y/b=1
and tell me the intercepts.

Answer 4

(3,5)

Answer 5

nice try, but the y-intercept is -5
because of the -*minus* sign in between
ok?

Answer 6

yeah that makes sense :)

Answer 7

now we write x-intercept as (a,0), here its (3,0)
and y-intercept as (0,b) here its (0,-5)
got this ?

Answer 8

That makes so much more sense..thanks for breaking it down

Answer 9

now can you plot (3,0) point on graph? where does it lie ?

Answer 10

where does it lie? you lost me..

Answer 11

i mean it lies on x-axis because y-coordinate =0
ok?

Answer 12

ok, had a blonde moment and wasn't sure if that was what you wre asking or not... sorry

Answer 13

solve for x=0 and y=0 you will get intercepts

Answer 14

:)

Answer 15

so when you plot both the points, just join them by a straight line , you would have graphed your equation.
need help plotting points ?

Answer 16

Nope that is the easy part.. the equations are what usually kick my butt.. more so figuring out how to right the equation out. you have been awesome.

Answer 17

welcome ^_^
and thanks for the compliment :)

Answer 18

:D no problem!
