Question

Find the x-, y-, and z-intercepts for the equation. 3x-5y+10z=15

Answer 1

set each one to 0 individually

Answer 2

3x-5y+10z=15

for z intercept 3x-5y+10*0=15
for y 3x-5*0+10z=15
for x 30-5y+10z=15

I think or something like that.

Answer 3

I still don't get :/. I got z=5y/3+5
y=5-10z/3
x=2z+3
but that doesn't make sense

Answer 4

You need to set BOTH the others = to 0 :)

Answer 5

Hmmm okay i'll try that lol i think i get it now

Answer 6

It should work. If you think about what you are doing when you find an intercept, you are finding a point on a given axis, therefore the values of the other coordinates are 0. If you are on the y-axis, y will be a value, but x and z are 0 :)

Answer 7

maybe this will help

Answer 8

Okay so far i got 5 for the x intercept.

Answer 9

That means you've got the right idea ;)

Answer 10

So i got x intercept=5,
y intercept= -3
z intercept= 3/2
is that right :O?
