What's the intercepts for the equation 4x-6y-5z=60?

Rudik [331]

To find the $x_i$ intercept, set $x_j=x_k=0$ . By this I refer to the following procedure.

x-intercept: Set $y=z=0$ , then you're left with $4x=60\iff x=15$ . Then the x-intercept is $(15,0,0)$ .

y-intercept: Set $x=z=0$ , then $-6y=60\iff y=-10$ . The y-intercept is $(0,-10,0)$ .

z-intercept: Set $x=y=0$ , then $-5z=60\iff z=-12$ . The z-intercept is $(0,0,-12)$ .

Wrich expreson is equivalent to 4(3-6).

Korvikt [17]

You haven’t provided any option, however I think I can still help.

You can solve 4(3-6). You first deal with he parenthesis, and get 4(-3). This means that your expression is equivalent to -12.

Hope this helps :)
